Figure 1

The mean (±se) overall proportion correct on the NaCl vs. KCl discrimination task collapsed across all NaCl and KCl trials on the last 6 presurgical test sessions without amiloride treatment. The different symbols represent the performance of individual rats and are consistent within a specified group across all figures. It is clear that all of the groups were displaying high levels of performance in the task before surgery. SHAM: Sham-operated controls; GLx: permanent bilateral transection of the glossopharyngeal nerve; CTr+GLx/GLr: bilateral regeneration of the chorda tympani nerve coupled with either bilateral regeneration of the glossopharyngeal nerve or permanent bilateral transection of the glossopharyngeal nerve; CTx: permanent bilateral transection of the chorda tympani nerve; CTx+GLr+GLx: unilateral regeneration of the glossopharyngeal nerve coupled with contralateral permanent transection of the glossopharyngeal nerve and permanent bilateral transection of the chorda tympani nerve; CT-PostTongue: bilateral cross anastomoses of the central portion of the chorda tympani nerve with the peripheral portion of the glossopharyngeal nerve resulting in bilateral reinnervation of the posterior tongue taste buds by the chorda tympani nerve coupled with lack of taste nerve innervation of the anterior tongue; GL-AntTongue: bilateral cross anastomoses of the central portion of the glossopharyngeal nerve with the peripheral portion of the chorda tympani nerve resulting in bilateral reinnervation of the anterior tongue taste buds by the glossopharyngeal nerve coupled with lack of taste nerve innervation of the posterior tongue.
