Cognitive Flexibility: How the Brain Learns New Rules to Navigate the Changing World

In everyday life, our brains adapt to new situations using the prefrontal cortex. A team of neuroscientists discovered a special class of neurons in the prefrontal cortex that enable flexible behavior, and when malfunctioning, may contribute to conditions like schizophrenia and bipolar disorder. These long-range inhibitory connections synchronize gamma oscillations across the left and right prefrontal cortex, allowing the brain to change its behavior at the right moment. This research could lead to new treatments for psychiatric conditions by targeting these long-range inhibitory connections.

Food for Thought: Nutrient Intake Linked to Cognition and Healthy Brain Aging

A new study reveals that nutrient intake, brain structure and cognitive function jointly contribute to brain health in older adults. The research discovered that blood markers of certain fatty acids are linked with better memory and larger brain structures in certain areas, suggesting the value of a comprehensive approach to diet and nutrition to promote healthy aging.

Sleep Problems in Children With Autism Linked to Fat Molecules

Study reveals a potential causal link between reduced levels of long-chain polyunsaturated fatty acids in blood plasma and poor sleep quality and disrupted sleep patterns in children on the autism spectrum. Researchers also found lipidome signatures in autistic children with sleep disorders were similar to signatures associated with an unhealthy diet.

AI-Equipped Eyeglasses Read Silent Speech

Researchers have developed a wearable interface called EchoSpeech, which recognizes silent speech by tracking lip and mouth movements through acoustic-sensing and AI. The device requires minimal user training and recognizes up to 31 unvocalized commands. The system could be used to give voice to those who are unable to vocalize sound or communicate silently with others.
