Scientists explore how dopamine shapes myelin in social isolation

Scientists know that social isolation can alter brain structure and lead to the breakdown of myelin, the fatty coating that insulates nerve fibers in the brain. But they don't yet know exactly how or why it happens.

Brain wave coordination explains how each hemisphere shares visual information

The brain divides vision between its two hemispheres-what's on your left is processed by your right hemisphere and vice versa-but your experience with every bike or bird that you see zipping by is seamless.

Texas Tech research team earns $3 million renewal to advance stroke therapy

Stroke research aims to understand the brain's self-protective and repair mechanisms. Gaining detailed insight into these mechanisms is crucial as such knowledge could lead to newly developed medications and interventions which mimic or engage the brain's self-protective/repair mechanisms, leading to innovative stroke therapies.

Rare ABCA7 gene variants linked to Alzheimer’s risk

A new study from MIT neuroscientists reveals how rare variants of a gene called ABCA7 may contribute to the development of Alzheimer's in some of the people who carry it.

Rapid neuronal evolution linked to high prevalence of autism in humans

A new paper in Molecular Biology and Evolution, published by Oxford University Press, finds that the relatively high rate of Autism-spectrum disorders in humans is likely due to how humans evolved in the past.

Chronic stress and fatty diet disrupt brain-liver circuit leading to diabetes

This study discovered a circuit in the brain that connects stress with increased glucose and therefore may link stress to type 2 diabetes. In stressful situations, this circuit from the amygdala to the liver naturally provides a burst of energy.

Glutamate receptors found to drive pediatric brain tumor development

The most common type of brain tumor in children, pilocytic astrocytoma (PA), accounts for about 15% of all pediatric brain tumors.

Can honey protect your brain? Study reviews its potential against Alzheimer's

This review examined 27 preclinical studies on honey and Alzheimer’s disease, showing honey’s bioactive compounds counter oxidative stress, inflammation, and amyloid buildup. Despite promising lab results, no human trials exist, underscoring the need for clinical research.

Stress in mothers causes eczema in newborn mice through immune cell changes

Maternal prenatal stress in mice disrupts fetal mast cell programming, triggering eczema-like skin inflammation and heightened sensitivity after birth. The findings reveal how corticosterone-driven immune and neuronal changes in utero may set the stage for pediatric eczema risk.
