An overview from rhesus of the response profiles of 51 single CT fibers. Area of circles: impulse activity over the first 5 s of stimulation. Open circles: inhibition. Absence of a mark: data are missing. The stimuli were arranged along the X-axis in order of salt, sour, bitter, and sweet. The fibers were arranged along the Y-axis in groups: NaCl-, acid-, QHCl-, and sucrose-fibers. MSG, monosodium glutamate; GMP, guanosine 5’-monophosphate. [46]
