Single Brain Synapse Pinpointed as the Starting Point of Vocal Learning
Scientists found that a single type of synapse in the basal ganglia is the origin of vocal learning. Disabling it makes birds revert to babbling.
Neurofeedback Trains Brain to Stop Depressive Rumination
Real-time fMRI neurofeedback gamifies brain training to reduce depressive rumination by targeting the neural coupling between self-referential and goal-directed brain regions.
Brain Signal Predicts and Restores Attention in Children
Researchers identified a neural signature that predicts attention lapses milliseconds before they occur. Targeted stimulation at that exact moment restored focus in children with ADHD and epilepsy.
Genetic Risk for Schizophrenia Alters Teen Brain Growth
A new study of over 6,000 children shows that high genetic risk for schizophrenia causes frontal brain surface area to shrink in early adolescence, while peers' brains grow.
LinCx: Biological "Bypasses" Restore Brain Circuits
Researchers engineered proteins that act as biological wires to reconnect broken brain circuits, altering behavior in mice without drugs or electrodes.
New Gene PTCHD1-AS Specifically Affects Autism Social and Repetitive Behaviors, Not Cognition
Researchers identify PTCHD1-AS, a long non-coding RNA gene that regulates social interaction and repetitive behaviors without affecting learning or memory, offering a precision target for autism traits.
Three Genetic Pathways Link Cannabis Use Disorder to Psychosis Risk
New research identifies over 500 genetic markers and three distinct biological pathways that explain how cannabis use disorder may lead to psychosis, offering a foundation for risk prediction and targeted treatments.
How Hormones Shape Hearing: Why Men and Women Process Sound Differently
New research reveals that hormonal fluctuations cause sex-dependent differences in hearing, challenging male-centric medical models and calling for precision audiology.
How the Timing of Trauma Shapes Brain Development and Behavior
A new study reveals that when trauma occurs—childhood, adolescence, or young adulthood—determines which brain regions are affected and which behaviors emerge, opening doors for personalized treatments.
Spatiotemporal AI Reveals How Brain's Motion Maps Self-Organize
New research shows that direction-selective maps in the brain's MT area emerge from a trade-off between task-driven learning and spatial smoothness, unifying visual stream theories.
Decoding Visual Neurons with Language: A New AI Method
Researchers used AI to translate monkey visual neurons into human-readable descriptions, correctly predicting neuron responses 96% of the time.
Finding the Sleep Sweet Spot for Slower Biological Aging
Sleeping less than 6 or more than 8 hours speeds aging across 17 organ systems, finds a new study of 500,000 people. The optimal sleep window is 6.4–7.8 hours.
