Neurobiological Component Report

Name	Error-related positivity
Description	The ERN is often followed by a positivity, known as the error-related positivity or Pe. The Pe is a positive deflection with a centro-parietal distribution. When elicited, the Pe can occur 200-500ms after making an incorrect response, following the error negativity (Ne, ERN), but is not evident on all error trials. In particular, the Pe is dependent on awareness or ability to detect errors.
No. of Studies (Positive/Negative)	4 (4/0)

2. User can drag the nodes to rearrange the layout of the network. Click the node will enter the report page of the node. Right-click will show also the menus to link to the report page of the node and remove the node and related edges. Hover the node will show the level of the node and hover the edge will show the evidence/description of the edge.
