Mitochondria in the Brain’s Reward Hub Drive Nicotine Dependence

Summary: Supported by a $943,000 NIH grant, neuroscientists at the University of Central Florida are investigating how nicotine alters neuronal mitochondria within the nucleus accumbens. By examining the subcellular mechanisms…

Cell Membrane Lipid Governs Retinal Light Sensitivity

Summary: Using cryogenic electron microscopy and synthetic model membranes, researchers have mapped how the membrane phospholipid PIP2 binds to cyclic nucleotide-gated (CNG) ion channels in retinal rod cells. Even at…

Can Humor Treat Depression? – Neuroscience News

Summary: A comprehensive review of clinical psychology and neuroimaging research shows that while humor can build resilience and protect against depressive relapse, it often does more harm than good during…

Five Brain Profiles of Depression Identified

Summary: Researchers using magnetoencephalography (MEG) identified five distinct neurophysiological subtypes of major depressive disorder based on functional brain connectivity. The findings show that patients sharing the same clinical diagnosis can…

Ancient Midbrain Circuit Decodes Social Escape Cues

Summary: Researchers at UC San Diego discovered an evolutionarily conserved midbrain circuit that detects the escape movements, and sudden disappearances, of social partners to trigger rapid collective avoidance. Using transparent…

How the Visual Cortex Maintains Stable Vision Amid Neural Fluctuations

Summary: Using a minimal mathematical rate model of the primary visual cortex, computational neuroscientists found that two intrinsic feedback mechanisms—rapid inhibition and homeostatic regulation—can constrain chaos and slash neural variability…

Loneliness Erases Nearly 6 Healthy Years

Summary: A massive observational study of more than 277,000 adults reveals that loneliness and social isolation significantly shorten disease-free life expectancy, stripping men of nearly six years and women of…

Inflexible Math Brain: How Neural Circuit Glitches Block Problem Solving

Summary: Stanford University researchers analyzing brain activity and behavioral metrics in 8- to 10-year-olds found that children with developmental dyscalculia struggle to switch between and optimize math problem-solving strategies. Distinct…

The Placenta May Decide Autism Vulnerability

Summary: A new study in mice reveals that maternal immune activation during a precise gestational window triggers autism-like developmental disruptions exclusively in male fetuses. Researchers traced this vulnerability to damaged…

Nighttime Light Exposure Linked to Sleep Loss in Schizophrenia

Summary: A new study reveals that nighttime light exposure is strongly associated with objective sleep disruption in outpatients with schizophrenia, resulting in nearly an hour less total sleep per night.…
