This figure presents a similar overview of the response profiles of 33 NG single fibers with the use of a topographical method as in Fig. 12. Area of circles: impulse activity over the first 5 s of stimulation. Open circles: inhibition. Absence of mark: data are missing. Arrangement of stimuli the same. Observe that salt, acids and sweet stimulates the anterior tongue while bitter the back mimicking the distribution in human. [46]
