Fig. 4From: An artificial neural-network approach to identify motor hotspot for upper-limb based on electroencephalography: a proof-of-concept studyGrand averaged movement-related event-related potential (ERP) patterns of all subjects on both hemispheres. Contralateral movement-related ERPs are clearly observed. A gray area and an arrow represent the movement-related ERP period and the peak of movement-related ERPs, respectively. Note that the sign of y-axis is invertedBack to article page
