Scientists pinpoint brain region responsible for effortful helping behavior

An area of the brain specifically involved in putting in effort to help others out has been pinpointed by scientists.

What makes the human brain different? Study reveals clues

What makes the human brain distinct from that of all other animals — including even our closest primate relatives? In an analysis of cell types in the prefrontal cortex of four primate species, researchers identified species-specific — particularly h…

Eye movements in REM sleep mimic gazes in the dream world

When our eyes move during REM sleep, we’re gazing at things in the dream world our brains have created, according to a new study. The findings shed light not only into how we dream, but also into how our imaginations work.

Mapping the brain stem’s control of eating could lead to better treatments for obesity

A new paper looks outside this brain region and reviews the various brain pathways that meet in the brain stem to control feeding behavior, using a technique that offers an unbiased look at the neurons involved, which could offer targets for better ob…

What makes us share posts on social media?

What makes people share posts on social media? A new study reveals that we share the social media posts we think are most relevant to ourselves or to our friends and family.

Neurofeedback shows promise for addressing ‘chemo brain’

The pilot study is one of the first to indicate that neurofeedback could help address cognitive deficits of cancer patients experiencing ‘chemo brain.’

Distress leads to higher COVID vaccine rates, less adherence to distancing guidelines, study finds

People who were more distressed — showing signs of anxiety or depression — during the COVID-19 pandemic were less likely to follow some best practice recommendations from the Centers for Disease Control and Prevention, according to a new study. Howev…

Molecular mechanisms that underlie spatial mapping in the brain

Research in mice illuminates the molecular mechanisms that underlie spatial mapping in the brain. Scientists found that a gene called Fos plays a key role in helping the brain use specialized navigation cells to form and maintain spatial maps.

How the sounds we hear help us predict how things feel

Researchers have made an important discovery about the way our brains process the sensations of sound and touch. The new study reveals how the brain’s different sensory systems are all closely interconnected — with regions that respond to touch also i…

Surprising culprit worsens stroke, TBI damage

A new study provides for the first time the surprising evidence that four common nonexcitatory amino acids that usually make proteins which are essential to brain function, instead cause irreversible, destructive swelling of both the astrocytes that su…
