Fig. 3From: An artificial neural-network approach to identify motor hotspot for upper-limb based on electroencephalography: a proof-of-concept studyArchitecture of an artificial neural network (ANN) model used for EEG-based motor hotspot identification. The numbers of input nodes, hidden nodes, and output nodes were 63 (PSD features of 63 channels), 40 (empirically selected), and 3 (3D motor hotspot coordinates), respectivelyBack to article page
