The plot summarizes the effect of GA in the chimpanzee. These recordings included 13 single chorda tympani fibers before and after application of GA on the tongue. The stimuli are arranged in the order of salt, sour, bitter, and sweet along the y-axis. Every second row labelled “after GA” shows data obtained after GA. The fibers are arranged along the x-axis in groups: S-, Q-, and N-clusters. Absence of a mark shows that data are missing. [57]
