Gyrification brain abnormalities as predictors of outcome in anorexia nervosa.

abstract：:Linking observed and executable actions appears to be achieved by an action observation network (AON), comprising parietal, premotor, and occipitotemporal cortical regions of the human brain. AON engagement during action observation is thought to aid in effortless, efficient prediction of ongoing movements to support ...
