An overview of the response profiles of 49 single chorda tympani, CT, taste fibers of marmosets. The area of the circle represents impulse activity over the first five seconds of stimulation with impulse activity deducted during the first five seconds before stimulation. The size of the dots shows the intensity of a response. Open circles represent inhibition or absence of a response. Absence of a mark shows that data are missing. The stimuli were arranged along the X-axis in order of salty, sour, bitter and sweet. The fibers were arranged along the y axis in groups: NaCl, citric acid, QHCl and sucrose-best fibers. Note that there is no overlap between the fibers responding to bitter or sweet. We use the same topographical method in all overviews. [58]
