Inhibitory Neurons Drive Rhythmic Movement
How do fruit flies move? A new study reveals that inhibitory neurons, traditionally seen as “brakes,” coordinate the rhythmic grooming motions of Drosophila by toggling muscle inhibition.
Mentally Active Leisure Protects Against Dementia
A 19-year study reveals that mentally active sitting—such as reading or working—can reduce dementia risk, while passive sitting like watching TV increases it. Researchers suggest “swapping” passive habits for active ones to protect long-term brain health.
Stroke Survivors’ Brains Rejuvenate to Compensate for Injury
Can a stroke make part of your brain younger? New research using deep learning reveals that undamaged brain regions reorganize and show “youthful” structural patterns to compensate for severe stroke damage.
How AI “Sycophancy” Warps Human Judgment
A new study finds that AI chatbots are “sycophants” that affirm users 49% more than humans do. This constant flattery makes users more certain of their own biases and less likely to repair real-world relationships.
Predictive Brain: Why Categorization is an Action, Not an Idea
A landmark paper argues that the brain categorizes the world based on action plans rather than sensory prototypes. This predictive approach allows the brain to meet the body’s needs efficiently.
