A study conducted by University of Arkansas researchers reveals that neurons in the motor cortex exhibit an unexpected division of labor, a finding that could help scientists understand how the brain controls the body and provide insight on certain neurological disorders.

More than a quarter of children with autism spectrum disorder are also diagnosed with disruptive behavior disorders. For the first time, Yale researchers have identified a possible biological cause: a key mechanism that regulates emotion functions differently in the brains of the children who exhibit disruptive behavior.

The brain is more resilient than previously thought. In a groundbreaking experiment published in this week's issue of Nature, neuroscientists created an artificial circulation system that successfully restored some functions and structures in pig brains. The result challenges the notion that mammalian brains are fully and irreversibly damaged by a lack of oxygen.

University of Oregon neuroscientists report that two areas of the mouse brain combine representations of what is heard and anticipated, guiding behavior that leads mice to the best reward.

A new study led by researchers from the University of California, Irvine finds exercising in the morning, rather than at night, may yield better results.

A new study shows that a synthetic molecule developed by Oregon Health & Science University scientists stimulates repair of the protective sheath that covers nerve cells in the brain and spinal cord. The study demonstrates in mice that a synthetic molecule called sobetirome efficiently repairs damaged myelin without side effects.

A prescribed drug to treat high blood pressure has shown promise against conditions such as Parkinson's, Huntington's and forms of dementia in studies carried out in mice and zebrafish at the University of Cambridge.

Massachusetts General Hospital investigators have discovered the mechanism by which cells sense dysfunction of the proteasome -- a cellular component that degrades unneeded or defective proteins -- and respond in a previously undescribed manner, by editing the amino acid sequence of a key sensing protein.

Two papers appearing April 18, 2019 in the journal Cell Metabolism confirm that the circadian clock is an important factor in how the body responds to physical exertion. Based on this work alone, it's too early to say when the best time is for you to go for a jog. But at least in the lab, exercise in the evening seems to be more productive, although human lifestyles are much more complicated.
