Rats were trained to turn in one direction in a modified T-maze while in one drug state and in the opposite direction while in another drug state. Incorrect turns during training were punished with shock and for three of the transfer groups, shock was contiguously conditioned to a 10 KHz buzzer in the drug state and to a 1 KHz buzzer in the non-drug state. During no-shock testing, the dissociation subjects were tested for state-dependency while the transfer subjects were tested for transfer by reversing the buzzer previously associated with the particular drug state in training. The hypothesis, that the …

Anticholinesterase Action And Electroconvulsive Shock-Induced Disruption Of Taste-Illness Association, Terry J. Debriere
Electronic Theses & Dissertations
Electroconvulsive shock (ECS) interpolated temporally between the pairing of a novel taste and an induced gustatory illness prevents the taste from being associated with the illness (Kral, 1971). Physostigmine has been shown to protect against retrograde amnesic effects of ECS on learning of a passive avoidance task (Davis, Thomas, and Adams, 1971). Physostigmine protection of ECS induced disruption of a conditioned taste aversion was investigated using a 2 (physostigmine vs. saline) x 2 (ECS vs. sham shock) x 2 (conditioned vs. nonconditioned) x 2 (conditioning day vs. test day) factorial design with repeated measures over the last factor. Results indicated …
