Fig. 5From: Pathway-specific modulatory effects of neuromuscular electrical stimulation during pedaling in chronic stroke survivorsGrand pooled ERSP charts for three pedaling protocols of Cluster A, BA 6 for healthy subjects. Pedal phase dependent cortical responses were observed throughout the pedal cycle (x-axis) and in the selected frequency bands (y-axis, log scaled), warm and cold color indicates increased or decreased cortical activity relative to the mean spectrogram respectivelyBack to article page
