Presurgical Testing 10 5 30 0.1, 0.2, and 0.4 M NaCl and KCl [with or without 100μM amiloride] Semi-random
Postsurgical Testing 30 5 30 0.1, 0.2, and 0.4 M NaCl and KCl [with or without 100μM amiloride] Semi-random

Note: LH = limited hold, the amount of time (in seconds) the rat has to respond after sampling the stimulus. TO = time out (in seconds) for incorrect responses.

a

the alternation criteria used: 8, 6, 4, 2.

b

Stimuli were presented in randomized blocks of 6 without replacement.
