How childhood stress contributes to anxiety, depression

New research could help explain why stress early in life can create vulnerabilities to mood and anxiety disorders later on.

Extracellular vesicles help pass information between cells and onto offspring

New studies reveal that small, membrane-bound particles transported between cells have wide-ranging and long-term effects in the brain and throughout the body, from helping neurons communicate to passing the effects of stress onto the next generation. …

Evidence of restored vision in rats following cell transplant

Researchers have discovered that neurons located in the vision centers of the brains of blind rats functioned normally following fetal retina cell transplants, indicating the successful restoration of vision.

The reasons for hemispheric dominance in the brain

The left and the right hemispheres specialize in different tasks. However, it has not yet been fully understood how one hemisphere assumes dominance over the other when it comes to controlling specific functions. Biopsychologists have demonstrated in p…

Disrupted circadian rhythms may drive anxiety and exacerbate brain disorders

Sleep disruptions are associated with many brain disorders, including anxiety, dementias, and traumatic brain injury. While these disruptions are sometimes viewed as a side effect of brain disorders, new findings suggest that aberrant sleep-wake cycles…

New gene therapy reprograms brain glial cells into neurons

A new gene therapy can turn certain brain glial cells into functioning neurons, which in turn could help repair the brain after a stroke or during neurological disorders like Alzheimer’s or Parkinson’s diseases.

Music improves social communication in autistic children

Improved communication skills may be linked to increased connectivity between auditory and motor regions of the brain, researchers find.

Studies highlight lasting effects of early life stress on the genome, gut, and brain

Excessive stress during fetal development or early childhood can have long-term consequences for the brain, from increasing the likelihood of brain disorders and affecting an individual’s response to stress as an adult to changing the nutrients a mothe…

Genetic risk factor for CTE detected

Researchers have identified a genetic variation that may influence chronic traumatic encephalopathy (CTE) disease severity. TMEM106B is one of the first genes to be implicated in CTE. It may partially explain why some athletes present with severe CTE s…

How to eat healthfully: Double your portion size

People tend to eat more when they are given a larger portion of unhealthful food. A new study asks whether the same rule applies for healthful snacks.
