Infant Brain Turns Music into Movement by 12 Months
A new study shows babies process musical structure as early as 3 months, but spontaneous movement to music—and later beat-syncing—only emerges around 12 months.
C1 Neurons: Brainstem's Master Switch for Lasting Anxiety
St. Jude researchers found that C1 neurons in the brainstem's medulla can lock in week-long anxiety after trauma, and silencing them may block it entirely.
Random Sounds During Sleep Disrupt Memory Consolidation
A new University of Freiburg study shows random sound clicks during sleep alter slow-wave propagation and impair memory, even without waking sleepers or shortening sleep.
Brain's Hidden Wiring May Protect Cognition as Gray Matter Shrinks
New brain imaging study links healthy superficial white matter to better language skills and weaker cognitive impact from age-related gray matter loss.
AI Predicts Parkinson's Motor Severity from Brain Scans
A new machine-learning study shows QSM MRI and fMRI brain features can predict Parkinson's motor symptom severity, explaining 45.4% of variance with clinically close accuracy.
Geometry Offers New Way to Map Brain Synchrony During Social Exchange
A NeurIPS 2025 paper proposes using discrete geometry and curvature entropy to detect key shifts in interbrain connectivity during social interaction.
Inflammation Pushes Brain Stem Cells to Stop Making New Neurons
A King's College London study found TNF-α forces human hippocampal stem cells into an immune alert state, halting new neuron growth — and an antibody reversed it.
Mild Heart Issues Linked to Microscopic Brain Damage and Memory Risk
A new study links weaker heart pumping to microscopic brain damage in memory regions, hinting at a connection that may raise the risk of memory loss later in life.
Mild Heart Issues Linked to Hidden Brain Decay in Alzheimer's Zones
A 3.5-year study of 73 cardiac patients finds that even subclinical heart dysfunction predicts microscopic tissue loss in memory-linked brain regions, explaining long-term cognitive decline.
AI Writing Erases Mystery and Complexity From Stories, Study Finds
New CASPER framework study from UNC Chapel Hill finds AI writing models strip narrative mystery, relying on safe archetypes and tidy endings — and bigger models don't fix it.
Why Some Brains Resist Alzheimer's: Rare Immature Neurons May Hold the Key
A Netherlands Institute for Neuroscience study of donated brain tissue finds that immature neurons in resilient brains activate survival programs and reduce inflammation, offering clues to cognitive resilience.
Psychedelics Amplify Cultural Context, Not Just Peace
A 21,990-person study shows psychedelics amplify whatever cultural mood surrounds the trip—unity on July 4th reduced partisan violence support, while election season increased it.
