An overview of the response profiles of 40 single CT taste fibers with the use of a topographical method. The area of the dots represents impulse activity per sec over 5 sec of stimulation. Absence of mark shows that data are missing. The stimuli were arranged along the x-axis in order of salty, sour, bitter and sweet and along the y-axis in groups: NaCl (N fibers), acids (H fibers), bitter (Q fibers) and sucrose best fibers (S fibers). Every second column showed the response to the sweetener with lactisole added.
