The mean (±se) overall proportion correct on the NaCl vs. KCl discrimination task collapsed across all NaCl and KCl trials on the first 5 postsurgical surgical test sessions. The different symbols represent the performance of individual rats and are consistent within a specified group across all figures. Transection of the GL alone had no effect on performance. Transection of the CT severely impaired performance which recovered if the CT regenerated into its native taste bud field in the anterior tongue. If the CT regenerated into the posterior tongue leaving the anterior tongue absent of taste innervation or if the GL regenerated into the anterior tongue leaving the posterior tongue denervated, performance was no better than the CTx group. In other words, neither cross-regeneration condition led to recovery of function. See Figure 1 caption for definition of group abbreviations.
