How the brain decides what to learn

Neuroscientists know a lot about how our brains learn new things, but not much about how they choose what to focus on while they learn. Now, researchers have traced that ability to an unexpected place.

Hallucinations associated with brain hyperactivity in people with macular degeneration

New research shows for the first time that visual hallucinations in people with macular degeneration are associated with abnormally heightened activity in the visual cortex of the brain. The findings could improve diagnosis of such hallucinations.

Mind’s quality control center found in long-ignored brain area

The cerebellum, once thought to be limited to controlling movement, is involved in every aspect of higher brain function, according to a new study.

Unique patterns of neural communications found in brains of children with autism

A research team studying MRI scans of school-age children’s brains found unique patterns of neural communication involving the amygdala, the area of the brain responsible for processing social information. In children with ASDs, the amygdala connection…

Surprising network activity in the immature brain

One of the outstanding mysteries of the cerebral cortex is how individual neurons develop the proper synaptic connections to form large-scale, distributed networks. Now scientists have gained novel insights from spontaneously generated patterns of acti…

Stress can impair memory, reduce brain size in middle age

Stress may be causing impaired memory and brain shrinkage in middle-age adults, even before symptoms of Alzheimer’s or other dementia begin, according to a new study.

Cannabis pain relief without the ‘high’

In the wake of cannabis legalization, a team of scientists have delivered encouraging news for chronic pain sufferers by pinpointing the effective dose of marijuana plant extract cannabidiol (CBD) for safe pain relief without the typical ‘high’ or euph…

How to recognize and cope with emotional exhaustion

Emotional exhaustion can arise after a period of excessive stress. Some people are more at risk than others, including those in demanding jobs or with caring responsibilities. People may not always recognize the signs of emotional exhaustion. Here, we …

Individual stress susceptibility and glucose metabolism are linked to brain function

Researchers have now discovered that stress-induced mental disturbances in mice are directly linked to abnormal glucose metabolism. Normalizing the stress-induced alterations in glucose levels, using the anti-diabetic drug empagliflozin, restored spati…
