Sleep phase can reduce anxiety in people with PTSD

A new study shows that sleep spindles, brief bursts of brain activity occurring during one phase of sleep and captured by EEG, may regulate anxiety in people with post-traumatic stress disorder (PTSD).

Stress increases Alzheimer’s risk in female mice but not males

Stress causes the levels of Alzheimer’s proteins to rise in females’ brains but not males’ brains, according to a new study. This difference may contribute to women’s greater risk of developing Alzheimer’s disease.

Machine learning model sheds light on how brains recognize communication sounds

Scientists studied guinea pigs’ communication to understand how the brain recognizes communication sounds regardless of accents and surrounding noise.

Scientists discover anatomical changes in the brains of the newly sighted

Neuroscientists discovered anatomical changes that occur in the white matter of visual-processing areas of the brain, in children who have congenital cataracts surgically removed.

Evidence of conscious-like activity in the dying brain

A new study provides early evidence of a surge of activity correlated with consciousness in the dying brain.

Structured exploration allows biological brains to learn faster than AI

Neuroscientists have uncovered how exploratory actions enable animals to learn their spatial environment more efficiently. Their findings could help build better AI agents that can learn faster and require less experience.

Mental imagery a helpful way to distract teens from negative thought patterns

For adolescents who may get stuck in negative thought spirals, refocusing on mental imagery is a more effective distraction than verbal thoughts.

Neuronal activity shapes the development of astrocytes

Researchers report that neuronal activity is necessary and sufficient for astrocytes to develop their complex shape, and interrupting this developmental process results in disrupted brain function.

Immune system sculpts rat brains during development

Researchers have identified the mechanism for why and how one brain region differs in size between male and female rats. The study found that immune system cells in the brains of females consume and digest neurons to sculp a region of the brain during …

Brain circuits for locomotion evolved long before appendages and skeletons

Scientists found parallels between the neural circuitry that guides locomotion in sea slugs and in more complex animals like mammals.
