  • F2-a  When more than one reference is listed for a given task, the numbers indicate which reference refers to which result.

  • F2-1002  Conditioned shock avoidance taste discrimination task.

  • F2-c  Two-lever operant taste discrimination task.

  • F2-1004  Amiloride, which inhibits a portion of the NaCl-evoked taste activity in the facial nerve (Heck et al., 1984;Brand et al., 1985; Sollars et al., 1997), completely impairs NaCl versus KCl discrimination performance (Spector et al., 1996a).

  • F2-e  Taste aversion generalization task. AlthoughSt. John et al. (1997) failed to replicate the severity of CTX-induced deficits in the acquisition of a NaCl CTA seen by Yamamoto et al. (1994b), seventh nerve neurotomy causes profound deficits (Spector et al., unpublished observations).

  • F2-1006  Response of furosemide-injected rats to an array of chloride salts.
