A new study shows how individual brain cells in the hippocampus respond to pronouns. “This may help us unravel how we remember what we read.”

Read the following sentence: “Donald Trump and Kamala Harris walked into the bar, she sat down at a table.” We all immediately know that it was Kamala who sat at the table, not Donald. Pronouns like “she” help us to understand language, but pronouns can have multiple meanings. Depending on the context, we understand who the pronoun is referring to. But how is it that we are so good at this, and how does our brain link pronouns with their nouns?

To answer this question, an international team of neuroscientists, neurosurgeons, and neurologists joined forces. Doris Dijksterhuis and Matthew Self from Pieter Roelfsema’s group looked together with their colleagues at the brain activity of patients with epilepsy. As part of their treatment, these patients were implanted with depth electrodes in their hippocampus, a brain area involved in learning and memory. The research team took advantage of this and conducted additional tests with them.

“We can measure the activity of individual brain cells in the hippocampus while the patient performs a task,” says Matthew Self. In the hippocampus, there are cells that respond to a specific person, so-called “concept cells.” A well-known example is the “Jennifer Aniston cell,” which becomes active when you see a photo of Jennifer Aniston, hear her name or read the words “Jennifer Aniston”. We wondered if these cells also become active when you only read a pronoun, like ‘he’ or ‘she’. Are these cells able to link the pronoun to the right person?

Shrek cell

Doris Dijksterhuis: “To test this, we first showed the patients many photos until we found a cell that responded to one particular image. For example, we found a cell that responded to an image of ‘Shrek’ but not to other images. We call this cell a ‘Shrek concept cell’. When patients later read a sentence like: “Shrek and Fiona were having dinner. He poured out some wine.” the ‘Shrek’ cell indeed responded to the word “Shrek”, but also to the pronoun ‘He.’ This is interesting because such a pronoun can mean something entirely different in another sentence. For example, in the sentence ‘Donald Trump and Kamala Harris were having dinner. He poured out some wine,’ the same pronoun, ‘He’, refers to Donald Trump, and therefore the Shrek cell will not react. Individual hippocampal cells track who the pronoun refers to in a dynamic, flexible way.”

Self: “We had the participants answer a question at the end of the sentences about who performed the action. We could predict whether the patients would give the correct answer based on the activity of the individual concept cells. To make it a bit more challenging, we also added some trick questions, with two people of the same gender: “Jennifer Aniston and Kamala Harris walked into a bar. She sat at the table.” The patient had to decide themselves who performed the action. We observed that patients tended to choose the person that evoked the most activity in the hippocampus at the start of the sentence. This could be based on chance fluctuations in activity on a trial-by-trial basis or an internal preference for one of the two characters in the sentence.”

The bigger picture

Dijksterhuis: “The hippocampus is important for learning and memory, but it remains unclear how the hippocampus is involved in the interaction between memory and language. How do we remember what we’ve read? When you think of something you’ve read, you have different concepts that together create the story. Pronouns help us to understand who did what in the story and cells in the hippocampus encode these actions into our memory. Ultimately, we want to know how an entire memory is formed and represented in the brain.”

“It is of great value that this group of patients has given their permission to participate in our research. We can only very rarely measure the activity of single brain cells in people who are reading and it is impossible to study these processes in animals. When we get the chance, we try to get as much out of it as possible.”

Researchers from three of Virginia’s premier universities, including the University of Virginia’s Homa Alemzadeh, aim to take the risk out of self-driving vehicles by overcoming inevitable computer failures with good engineering.

The trio will share a $926,737 National Science Foundation award to identify when and where autonomous vehicle systems are most vulnerable to safety-critical failures. They plan to use this knowledge to design ways to efficiently mitigate potential safety hazards and enhance the overall system resilience. 

Alemzadeh, an associate professor of electrical and computer engineering in UVA’s School of Engineering and Applied Science, is collaborating with William & Mary professor of computer science Evgenia Smirni, and George Mason University assistant professor of computer science Lishan Yang, the lead investigator.

Alemzadeh said recent studies show a significant portion of “disengagements,” in which the autonomous system is turned off by the system or a human driver for safety reasons, happen when the machine learning-based AI makes wrong decisions, or doesn’t make them in time.

“We are particularly interested in studying disengagements and safety incidents due to transient hardware faults, temporary loss of network connection or software errors,” she said.

Hunting Elusive Vulnerabilities

These often self-correcting events may cause only a momentary disruption, and then they’re gone, making them hard to find and diagnose.

For safety and reliability, self-driving vehicles depend as much on the software “controller” that makes and executes decisions for autonomous operation and machine learning components as physical parts such as sensors and brakes. 

If transient faults are activated at a critical operational time, they can propagate throughout the system’s hardware and software layers, evade existing safety checks and create hazards.

“We aim to look at the end-to-end system — from input to output — to investigate the critical fault locations within the hardware and software, as well as the system contexts that lead to activation of faults and safety hazards,” Alemzadeh said.

The researchers will focus on improving controller and machine learning components to prevent accidents. Using cross-layer reliability analysis, they plan to strategically target the most critical faults in the vast, complex software code and hardware that underlie the controller and machine-learning models.

Test-Driving Solutions in Real Time

Based on when and where they find vulnerabilities, the team will design protection mechanisms —such as automatically correcting transient faults or mitigating unsafe vehicle operations by automatically slowing down — that can be applied selectively at different times and locations to ensure safety while maximizing efficiency.

The team will validate their solutions through closed-loop testing in which the autonomous system and its safety features will be tested in real time using driving simulations under varying weather, road and traffic conditions. They will concurrently simulate faults and errors to assess those impacts and the performance of their solutions.

The three-year NSF project, End-to-End Resilience in Autonomous Driving Systems: Strategic Vulnerability Assessment and Mitigation, follows a previous collaboration between Alemzadeh and her colleagues. Toward Trustworthiness in Autonomous Vehicles, funded by the Commonwealth Cyber Initiative Coastal Virginia regional node, laid the groundwork for the current project.

With four regional nodes, the Commonwealth Cyber Initiative is a coalition of state higher education institutions that partners with government, industry and non-government organizations to make Virginia a global leader in cybersecurity through research, innovation and workforce development. 

Alemzadeh also is a member of UVA Engineering’s Link Lab, a multidisciplinary research and education center for cyber-physical systems, and holds a courtesy appointment in computer science.


Unexpected human behaviour revealed in prisoner's dilemma study: Choosing cooperation even after defection




 News Release 

Rissho University





The study also examined the impact of different game structures, such as simultaneous versus alternating decision-making, and the option of voluntary participation. The results showed that these variations significantly influence participants' cooperation rate.

The research reveals that people tend to cooperate even after being defected, which contradicts many traditional game theory models. "This finding is particularly fascinating because it suggests that humans are more forgiving and cooperative than previously thought," said Dr. Hitoshi Yamamoto, the study's lead researcher.

The study's findings suggest that current models of game theory may need to be revised to better reflect the complexity of human behaviour. The researchers hope that their work will inspire further studies into the nuanced nature of cooperation and competition among people.

Kombucha is a fizzy, tangy drink made by fermenting tea. But brewers are now fermenting other plant-based drinks to explore nutritional properties and flavors. Researchers in ACS Agricultural Science & Technology compared the biochemistry and flavor of kombucha with brews made from apple and passion fruit juices. They found that the apple beverage contained high levels of bioactive compounds called flavonoids and ranked highly among taste testers, signaling its promise as a kombucha alternative.

To make kombucha, brewers ferment sweetened tea with a spongy disk of microbes known as a SCOBY, or symbiotic culture obacteria and yeast. The resulting beverage contains beneficial bacteria from the fermentation process and bioactive compounds from the tea, including flavonoids, phenolics and anthocyanins that may have antioxidant and anti-inflammatory properties. Few studies have investigated whether liquids other than tea could be brewed as kombucha-like beverages with boosted antioxidant levels or unique flavors. So, Socorro Vanesca, Frota Gaban and coworkers fermented antioxidant-rich apple and passion fruit juices with a SCOBY to find out.

After fermenting apple juice, passion fruit juice, and tea in separate jars for 10 days at room temperature, the researchers measured the levels of several bioactive compounds in each brew and found that:

  • The apple beverage had the highest level of flavonoids, followed by kombucha and the passion fruit drink.
  • The kombucha and apple beverages had comparable levels of phenolic compounds that were higher than those of the passion fruit beverage.
  • All three brews had similar amounts of anthocyanin, a red-colored antioxidant.

The researchers asked 12 volunteer taste testers to evaluate each beverage’s color, aroma and flavor. The taste testers noted an amber color for the apple beverage, yellow for passion fruit and gold for the kombucha. The volunteers reported stronger, fruitier aromas for the fermented fruit juices compared with the tea. However, the passion fruit drink tasted more bitter than the sweeter apple and tea drinks, both of which received equal votes as the favorite beverage. Because fermented apple juice has more flavonoids and a pleasant taste compared with the other beverages, the researchers say it could be a successful alternative to kombucha made from tea. They plan to explore health benefits and flavors of other fermented fruits in the future.

The diverse biochemical composition of Japanese apricot fruits explains their broad spectrum of action on the human body. The high levels of key phenolic compounds and hydroxycinnamic acids contribute to various health benefits including anti-inflammatory, antioxidant, and antimicrobial properties.

A recent study published in Food Research International on July 19, 2024, led by Prof. Yukiharu Ogawa and Jutalak Suwannachot from Chiba University, quantitatively evaluated the changes in phenolic compounds and antioxidant activity during the production of Shiso-zuke Umeboshi (PP). The study also simulated the digestive process to characterize the release of these compounds and their antioxidant activity.

“Some of the benefits have been observed in pickling with red perilla (PP), but the current data are still limited. Many recent efforts have been focused on creating functional foods, which are designed to provide health benefits and essential nutrients in addition to the traditional micronutrients. However, there remains uncertainty regarding the specific effects of apricot pickled with red perilla (Shiso-zuke Umeboshi, PP). This motivated our study,” explains Prof. Ogawa.

In this study, the production of perilla-pickled apricots involved three methods: simple salt pickling (SP), pickling with salted perilla leaves for 30 days (30-PP), and pickling with salted perilla leaves for 60 days (PP). The pickle samples underwent ultrasonic-assisted treatment, after which the supernatants were extracted from the mixture by centrifugation to quantify free and esterified phenolics in the aqueous phase. The remaining residue was used to analyze the insoluble-bound phenolics in the organic phase.

All three phenolic fractions were assessed using liquid chromatography-mass spectrometry (HPLC-PDA-QDa), with a focus on their peak areas at 280 and 320 nm wavelengths.

The researchers evaluated total phenolic content (TPC) using the Folin-Ciocalteu reagent test. The Total flavonoid content (TFC) was determined via a 96-well microplate method combined with an aluminum chloride (AlCl3) colorimetric assay. Antioxidant activity was then assessed at 740 nm, with results expressed in millimoles (mmol).

The scientists modeled the gastrointestinal digestion of apricot pickles. They adjusted the sample’s pH to simulate the conditions of the different parts of the digestive tract. Next, digestive enzymes were introduced, and the digested fractions were filtered. The components were then identified, and their antioxidant activity was measured.

The HPLC chromatogram revealed rosmarinic, caffeic, p-coumaric, and ferulic acids as the main phenolic compounds detected. A comparative analysis of the three samples showed an increase in the concentration of bioactive compounds from the 30-day pickling stage (30-PP) to the finished product (PP). Among all phenolics, rosmarinic acid (RA) was the most predominant in all the samples. Ferulic acid was detected in smaller concentrations, particularly in esterified fractions that also showed higher levels of caffeic and p-coumaric acids. The lower concentration of ferulic acid is likely due to its low water solubility.

In the simulated in vitro digestion, differences between salt pickling (SP) and salt pickling with perilla (PP) were analyzed at various stages: before digestion (G0), 60 minutes after gastric digestion (G60), at the transition to intestinal digestion after 60 minutes (G60), and 120 min into small intestinal digestion (I120).

The highest release of bioactive compounds occurred at G0, while the lowest levels were observed at G60. However, a significant increase in bioactive compound release was noted between G60 and I120. At I120, both SP and PP showed the highest release of TPC and TFC. These results can be attributed to the influence of pH conditions and intestinal enzymes, which likely enhanced TPC and TFC levels.

For antioxidant activity, PP demonstrated a higher potential throughout the in vitro gastrointestinal digestion from 1 hour of gastric digestion through the final stage of small intestinal digestion, in contrast, SP exhibited a more steady trend. Overall, the acidic conditions during pickling appear to enhance the availability of RA and other perilla compounds.

“The health benefits of Japanese apricot pickles are mainly derived from the antioxidant compounds of the red perilla, which acts as both a natural food color and a health-promoting ingredient,” concludes the lead researcher Jutalak Suwannachot.

Artificial intelligence may enhance patient safety, say BU researchers


Study marks an important first step towards leveraging AI technology to reduce preventable harms, achieve better healthcare outcomes




Boston University School of Medicine




(Boston) — Generative artificial intelligence (genAI) uses hundreds of millions, sometimes billions, of data points to train itself to produce realistic and innovative outputs that can mimic human-created content. Its applications include personalized recommendations for online shoppers, creating audio and visual content and accelerating engineering design. In healthcare, possible genAI uses include enhancing imaging technologies, predicting the course of a disease in an individual patient and discovering new vaccines.

BU researchers tested an advanced publicly available genAI model, GPT-4, to determine its ability to answer questions across five key areas of patient safety in the 50-question self-assessment for the Certified Professional in Patient Safety (CPPS) exam, a standardized multiple-choice certification exam for patient safety professionals. GPT-4 answered 88% of the questions correctly, demonstrating a high level of performance.

“While other studies have looked at genAI's performance on exams from different healthcare specialties over the past year, ours is the first robust test of its proficiency specifically in patient safety,” said corresponding author Nicholas Cordella, MD, MSc, assistant professor of medicine at BU Chobanian & Avedisian School of Medicine. 

James Moses, MD, MPH, formerly an associate professor of pediatrics at the school and now chief  of quality, safety and patient experience at Corewell Health in Michigan, is a co-author of the study.

The researchers presented questions from the CPPS self-assessment exam to the GPT-4 model without any additional training or medical fine-tuning. They then evaluated the model's performance across various exam categories. They found GPT-4 performed particularly well in the domains of Patient Safety and Solutions, Measuring and Improving Performance, and Systems Thinking and Design/Human Factors. Based on the strength of those results, the researchers outlined areas where patient safety professionals could begin to conduct more testing of the real-world strengths and weaknesses of AI.

“Our findings suggest that AI could help doctors better recognize, address and prevent mistakes in hospitals and clinics. While more research is needed to fully understand what current AI can do in patient safety, this study shows that AI has some potential to improve healthcare by assisting clinicians in addressing preventable harms,” said Cordella who also is medical director for quality and patient safety at Boston Medical Center.

He believed the use of AI holds promise for improving patient safety systems and better tackling the intractable problem of medical errors, which are estimated to cause approximately 400,000 deaths every year.

Cordella said the study aligns with the broader idea that AI can help professionals, including doctors, enhance their work. By using AI to support their tasks, clinicians may be able to improve the safety and efficiency of healthcare, similar to how other knowledge workers are adapting AI to boost their performance.

The study also revealed limitations in current AI technology and cautioned that users must remain vigilant for bias, false confidence, fabricated data or hallucinations in large language model (like GPT-4) responses.

"Our findings suggest that AI has the potential to significantly enhance patient safety, marking an enabling step towards leveraging this technology to reduce preventable harms and achieve better healthcare outcomes. However, it's important to recognize this as an initial step, and we must rigorously test and refine AI applications to truly benefit patient care," said Cordella.

These findings appear online in the Joint Commission Journal on Quality and Patient Safety.

 

Alarming surge: Global crisis of childhood overweight and obesity



Researchers ‘sound the alarm’ in commentary

Since 1990, the rise in childhood overweight and obesity has surged across every continent, almost doubling in prevalence. While the United States has the highest prevalence, other nations are not far behind.

In Southern Europe, including Greece, Italy and Spain, 10 to 15% of children are obese, while Eastern European countries have somewhat lower rates, but are experiencing a rapid increase that may soon match Southern Europe. Globally, Asia has nearly half of all overweight children under the age of 5, and Africa has one-quarter of such children. In Latin America, about 20% of children under 20 are overweight. Many developing countries face the dual challenge of both overweight/obesity and malnutrition in their children.

The deleterious consequences of this epidemic are already evident: childhood hypertension, type 2 diabetes, among others. Researchers from Florida Atlantic University’s Schmidt College of Medicine and colleagues sound the alarm and discuss both challenges and potential solutions in a commentary published in The Maternal and Child Health Journal.

“Pediatric overweight and obesity have reached epidemic levels in the U.S. and are becoming a pandemic globally. These conditions lead to high blood pressure, type 2 diabetes and lipid disorders, which contribute to metabolic syndrome. In adults, these issues significantly increase the risks of heart attacks, stroke, liver disease, obstructive sleep apnea, arthritis and certain cancers – many of which are now occurring at younger ages,” said Charles H. Hennekens, M.D., first author and the first Sir Richard Doll Professor of Medicine and Preventive Medicine, FAU Schmidt College of Medicine. “Through coordinated clinical and public health efforts, we can address these troubling trends and work toward a healthier future for children and families globally.”

In the commentary, the authors report on the leading causes of this epidemic including high body mass index (BMI), which increases the risks of many serious health issues. In the U.S., a preschooler is considered overweight if their BMI exceeds the 85th percentile. Research shows that these children are at a significantly higher risk of being overweight during adolescence compared to those with a BMI at the 50th percentile. This underscores the misconception that children simply “outgrow” overweight issues.

In addition, the authors note that health care providers and public health practitioners face major challenges in boosting daily physical activity among children, which is crucial for increasing metabolic rates, lowering BMI, and reducing future risks of coronary heart disease.

“With declining physical education in schools and excessive time spent on electronic devices, many children fail to meet recommended activity guidelines. This sedentary behavior contributes to overweight and obesity through poor diet, reduced sleep, and decreased physical activity,” said Panagiota “Yiota” Kitsantas, Ph.D., co-author and professor and chair, FAU Department of Population Health and Social Medicine, Schmidt College of Medicine. “Encouraging organized, enjoyable activities rather than competitive ones can help children achieve necessary physical activity levels.”

The authors also caution that while increasing levels of daily physical activity is necessary, it isn’t sufficient to make a major impact on the rates of childhood overweight and obesity. The rise of high sugar containing foods, along with consumption of ultra-processed foods also are major contributors.

“Nearly 70% of the average U.S.-based child’s diet is made up of ultra-processed foods,” said Hennekens. “Moreover, consumption of ultra-processed foods among children under 24 months is rising worldwide, triggering not only the potential of developing obesity but also decreased immunological protection.”

The authors say that more research is needed to pinpoint which components of ultra-processed foods contribute to weight gain in children. However, they warn that a diet high in ultra-processed foods is linked to rising rates of overweight and obesity, with schools being a major source of these foods.

“Evidence suggests that enhancing school lunch nutritional standards could help reduce obesity, particularly among low-income children,” said Kitsantas. “We recommend adopting school food policies that remove ultra-processed foods from menus and promote healthier alternatives, alongside educational programs on healthy eating, despite the challenges posed by external influences on children.”

Among the challenges highlighted in the commentary is the use of social media and advertising, which significantly affect children’s food choices and behaviors that include sharing unhealthy food posts and recognizing many unhealthy food brands upon exposure. 

“Despite recommendations from the World Health Organization and public health authorities to restrict food marketing aimed at children, few countries have implemented such measures,” said Hennekens. “The effectiveness of existing regulations in today’s media landscape is uncertain, creating an opportunity for health providers and public health practitioners to educate families about the impact of this advertising.”

The authors explain that addressing the rising pediatric obesity epidemic requires a multifaceted approach. In 2023, the American Academy of Pediatrics endorsed WHO guidelines and released their own recommendations for managing pediatric overweight and obesity. These guidelines advise health care providers and public health practitioners to tackle social determinants of health, use motivational interviewing to modify nutrition and activity behaviors, and consider pharmacotherapy or surgery to meet personalized patient goals.

However, the authors say that while there are approved drug therapies available, before prescribing pharmacologic options, maternal and child health care providers should employ therapeutic lifestyle changes.

“While the ultimate goal is prevention of pediatric overweight and obesity as well as metabolic syndrome, to paraphrase Voltaire, we should not ‘let the perfect be the enemy of the good,’” said Hennekens.

In conclusion, the authors urge leveraging all available resources to at least stabilize the rising rates of childhood obesity and its associated health issues. Ignoring these challenges could lead to an unprecedented global epidemic of childhood and adolescent obesity, with severe future health consequences, as seen in the U.S.

“Health care and public health professionals must collaborate across disciplines to address these issues with patients, families, communities and policymakers. United efforts can help reverse these troubling trends and ensure a healthier future for children worldwide,” said Kitsantas.

Statement by NIH on research misconduct findings




NIH/Office of the Director



 

Following an investigation, the National Institutes of Health (NIH) has made findings of research misconduct against Eliezer Masliah, M.D., due to falsification and/or fabrication involving re-use and relabel of figure panels representing different experimental results in two publications. NIH will notify the two journals of its findings so that appropriate action can be taken. NIH initiated its research misconduct review process in May 2023 after it received allegations from the HHS Office of Research Integrity (ORI) that same month. NIH began its investigation phase in December 2023, concluded its investigation of these allegations on September 15, 2024, and notified HHS ORI of its findings.

 

Dr. Masliah joined the agency in the summer of 2016 as director of the Division of Neuroscience (DN) at the National Institute on Aging and an NIH intramural researcher investigating synaptic damage in neurodegenerative disorders. He has published numerous papers as an NIH intramural researcher. Currently, Dr. Masliah is not serving in the capacity of director of the NIA DN. Amy Kelley, M.D., NIA Deputy Director, is also serving as the Acting NIA DN Director. Beyond this information, NIH does not discuss personnel matters.

 

Any allegations involving Dr. Masliah’s NIH-supported extramural research prior to joining NIH would be referred to HHS ORI, consistent with NIH policies and procedures.
