How brain zapping could decrease psychiatric symptoms

Electrifying brain circuits could treat neurological and psychiatric symptoms not because it causes neurons to fire but it creates an environment that makes it more or less likely for neurons to fire, researchers, including one of Indian-origin, have found.

What makes some people binge drink while others stay sober

Alcohol can reduce firing of neurons or brain circuits, which is why it reduces anxiety and social inhibitions, and those who are less sensitive to motor-impairing effects of alcohol are likely to drink much, the researchers said.
