How the brain’s housekeeper malfunctions during bacterial meningitis

Bacterial meningitis is a life-threatening infectious disease of the brain that leaves many survivors with long-lasting neurological impairments. Now, researchers show in a study on rats that the brain’s tool for waste clearance, the glymphatic system,…

Half of moms of kids with autism have high depressive symptoms

About 50% of all mothers of children with autism spectrum disorder (ASD) had elevated levels of depressive symptoms over 18 months, while rates were much lower (6% to 13.6%) for mothers with neurotypical children in the same period, researchers report.

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.
