Human beings can sometimes experience dissociative states, moments in which they feel disconnected from their body and the world around them. While these states have been linked to many psychiatric conditions, they can also ...
Scientists looking to understand the fundamental brain mechanisms of autism spectrum disorder have found that a gene mutation known to be associated with the disorder causes an overstimulation of brain cells far greater than ...
