FIGURE 4.3

Recordings of submandibular salivary secretion, jaw movement, and licking from an unanesthetized rat. Each tracing consists of salivary flow rate (Salivation), electo-myographic activity of the left and right masseter muscles (L Mass, R Mass), and licking (Lick in records C and D). Observed behavior is indicated by a line underneath the traces. (A) Salivary secretion evoked by grooming. (B) Salivary secretion evoked by eating a food pellet. (C) Salivation in response to taste stimuli. Taste stimuli do not result in high flow rates of saliva. (Da and Db) Salivation in response to licking quinine, which is only briefly sampled but evokes prolonged salivation and mouth movements. (From Matsuo, R. et al., Brain Res., 649, 138, 1994.
