Brain Criticality May Hold Key to Learning, Memory, and Alzheimer’s
Summary: New research proposes a unified theory of brain function based on criticality—a state where the brain teeters between order and chaos, allowing it to learn, adapt, and process information…
One Gene Rewires Fear Circuits and Fuels Anxiety
Summary: Researchers have uncovered how losing the autism-linked gene PTEN in a specific set of inhibitory neurons reshapes brain circuits tied to fear and anxiety. Using advanced circuit-mapping techniques, they…
Exercise Proven to Boost Kids’ Mental Health
Summary: A massive analysis of over 375 trials shows that structured exercise significantly reduces depression and anxiety in children and teens. Low-intensity resistance activities like light weights were most effective…
How the Brain Forms Indirect Associations to Guide Complex Decisions
Summary: A new study reveals how the brain can make decisions based not only on direct experiences, but also on indirect associations between seemingly unrelated stimuli. In experiments with mice,…
