Max Entropy Principle Predicts Neural Network Structure Better Than Training
New research shows that maximum entropy, not just training, shapes neural connections. The principle predicts network structure observed in gradient descent across multiple learning regimes.
Machine Psychometrics: a new science to measure AI minds
Researchers propose Machine Psychometrics, a measurement science to assess AI behavior using tools from mathematical psychology, avoiding both over-anthropomorphism and mind-blindness.
Thalamic Oscillation: A Biological Signature of Consciousness Found
Researchers discovered a rapid 20-45 Hz oscillation in the thalamus that only appears when we are awake or in REM sleep, offering a biological signature for conscious states.
New Compounds May Block Alzheimer's Brain Inflammation Linked to APOE4 Gene
USC researchers identified experimental compounds that selectively inhibit the cPLA2 enzyme, reducing brain inflammation tied to Alzheimer's, especially in APOE4 carriers.
Growing a Neural Network in Breadth, Depth, and Time
A new study shows that neural networks can trade off breadth, depth, and time like resources, and their processing time mirrors human reaction times.
Astrocytes Fine-Tune Sodium Levels to Match Nearby Neurons, Upending Decades of Dogma
New research reveals that sodium concentrations in astrocytes are not uniform but vary by location to support local synaptic activity, overturning a long-held assumption in neuroscience.
Brain Protein Menin Decline Drives Aging, Reversed by Supplement in Mice
Declining levels of the brain protein Menin in the hypothalamus trigger inflammation, memory loss, and physical aging in mice. Restoring Menin or supplementing with D-serine reversed cognitive decline.
Heart Attack Toxin Methylglyoxal Damages Brain, Causing Depression and Cognitive Decline
A new study reveals that after a heart attack, the toxic byproduct methylglyoxal surges into the brain, driving depression, anxiety, and cognitive decline. A peptide therapy may trap this toxin.
Long COVID Brain Inflammation Naturally Decreases Over Time, Study Finds
A new neuroimaging study shows that widespread brain inflammation in Long COVID peaks early and fades within 16 months, shifting focus from anti-inflammatory drugs to emotional regulation therapies.
Vitamin B12 guidelines may be too low for brain health, UCSF study finds
Older adults with 'normal' but low-active B12 show slower thinking and more white matter damage, suggesting current guidelines may miss hidden brain risks.
Serotonin Reduces Belief Stickiness: New Hope for OCD Treatment
A new study shows serotonin reduces 'belief stickiness'—the tendency to cling to outdated ideas—offering a fresh understanding of OCD and a targeted treatment window.
175 Vicious Mental Health Loops Mapped in New Study
A new study maps 175 self-reinforcing loops connecting 29 factors that trap young adults in poor mental health.
