Brain Scans Reveal a Network Origin Point for Schizophrenia
Summary: A new study utilized specialized Positron Emission Tomography (PET) imaging to measure synaptic connections in the living human brain. Evaluating one of the largest clinical cohorts of its kind…
Testosterone Drives Early Pubertal Distress in Girls
Summary: Researchers analyzed longitudinal data from thousands of preteen girls. They discovered that testosterone, a hormone traditionally associated primarily with male development, plays a dominant, previously underestimated role in the…
Open-Source AI Tools for Alzheimer’s
Summary: Announced at the Alzheimer’s Association International Conference in London, the Consortium for Biomedical Research and Artificial Intelligence in Neurodegeneration (C-BRAIN) has officially launched three open-source AI tools. Built to…
Study Maps the 9 Distinct Types of Procrastinators
Summary: Researchers synthesized insights from hundreds of studies across psychology, behavioral economics, and neuroscience. The study reveals that procrastination is an intricate psychological battlefield driven by a fundamental evolutionary mismatch…
AI Chip Mimicking Brain’s Reflex Center Developed
Summary: Researchers unveiled a novel, cerebellum-inspired electronic chip. While most neuromorphic computing tries to recreate the thought-heavy cerebrum, this new device emulates the reflex-driven cerebellum, which ignores expected baseline data…
NFL Players Face Fourfold Increase in Neurodegenerative Mortality
Summary: A multi-institutional team evaluated health records spanning six decades. The investigators discovered that while former players have lower all-cause mortality rates overall, they are four times more likely to…
C1 Neurons Identified as Master Anxiety Switch
Summary: Researchers discovered that a specific subpopulation of epinephrine-producing cells, known as C1 neurons, act as master controllers of fear and persistent anxiety. Normally, these cells sound a brief, temporary…
When Hearing Voices Functions as a Coping Mechanism
Summary: Researchers launched a pioneering set of clinical resources, including a practical guide and a short documentary film. The project proves that hearing voices can often function as an adaptive,…
Astrocyte Subtype Shifts Destabilize Emotional Brain Networks
Summary: Researchers compiled emerging evidence to prove that astrocytes, traditionally dismissed as passive, structural “glue” cells, are active directors of neural circuitry and emotional processing. The investigators mapped the cellular…
