Cognitive phenotypes in parkinson's disease differ in terms of brain-network organization and connectivity.

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 ...
