Two powerful brain chemical systems work together to paralyze skeletal muscles during rapid eye movement (REM) sleep, according to new research in The Journal of Neuroscience. The finding may help scientists better understand and treat sleep disorders, including narcolepsy, tooth grinding, and REM sleep behavior disorder.

Raising levels of the neurotransmitter dopamine in the frontal cortex of the brain significantly decreased impulsivity in healthy adults, in a study conducted by researchers at the Ernest Gallo Clinic and Research Center at the University of California, San Francisco.

Neuroscientists have found strong evidence that vivid memory and directly experiencing the real moment can trigger similar brain activation patterns.

Severe psychological and physical neglect produces measurable changes in children’s brains, finds a study led by Boston Children’s Hospital. But the study also suggests that positive interventions can partially reverse these changes.

Scientists at Johns Hopkins have discovered a “scaffolding” protein that holds together multiple elements in a complex system responsible for regulating pain, mental illnesses and other complex neurological problems.
