EEG and MEG: Mapping Brain Networks in Milliseconds
Richard Leahy and Takfarinas Medani review how EEG and MEG map large-scale brain networks with millisecond precision, plus open-source tools like Brainstorm.
Monkeys, Kids, and Adults Share Geometry Intuition, Study Finds
A PNAS study finds baboons, macaques, preschoolers, and adults — including Bolivia's Tsimane' — match abstract 2D shapes using the same cognitive strategies.
Cooperation Without Altruism: New Study Rewrites the Prisoner's Dilemma
New PNAS simulations show cooperation emerges spontaneously when individuals respond differently to different partners — no kinship, reputation, or complex rules required.
Closed-Loop BCIs Could Target Depression and Anxiety
A Mount Sinai review outlines how cognitive brain-computer interfaces could detect and respond to psychiatric states in real time by tracking multi-region brain networks.
Brain Tumor Immunotherapy Success Depends on Neck Lymph Nodes, Study Finds
A KAIST study shows anti-CTLA-4 immunotherapy against brain tumors requires B-cell and antibody responses in deep cervical lymph nodes, not just local T cells.
Brain Protein Menin Linked to Aging; Restoring It Helped Mice
Lower Menin in the mouse hypothalamus tracked with inflammation, cognitive decline, and thinner skin. Restoring it improved memory and balance; D-serine also boosted cognition.
Newer Blood Thinners Linked to Slower Cognitive Decline in Alzheimer's
A Karolinska Institutet study of 7,308 patients found NOAC blood thinners were linked to slightly slower cognitive decline than warfarin or no treatment in people with Alzheimer's and atrial fibrillation.
Why 'That's Not How I Pictured It' Is a Real Cognitive Conflict
A cognitive aesthetics study traces the 'mind's eye' from 19th-century illustration panics to modern film adaptations, showing why visual adaptations clash with your internal imagery.
Locus Coeruleus: Targeted Norepinephrine Signals Drive Learning
Allen Institute study shows the locus coeruleus sends precise norepinephrine signals, not a broad broadcast, and contains the longest mouse axon at 70.32 cm.
How Adolescent Brain Remodeling Temporarily Hides Early Memories
A new study in mice reveals that perineuronal nets in the retrosplenial cortex temporarily break down during late adolescence, making early memories inaccessible before they resurface with less precision in adulthood.
New Alzheimer's Drug Repairs DNA Damage and Reduces Brain Inflammation
KCL-286, a drug originally developed for spinal cord injury, repaired DNA double-strand breaks and reduced inflammation in Alzheimer's mouse models. It has already passed Phase 1 safety trials.
Most Neurons Are Multi-Tasking Generalists, New Study Finds
A new Nature study shows most brain neurons are multi-tasking generalists, not specialists—reshaping how we understand cognition and neural computation.
