Summary:
To investigate dissociated (state dependent) learning of a classically conditioned heart rate response, 24 rats were trained either normally or under cortical spreading depression (CSD). Testing in extinction for experimentals was carried out over two days with Ss experiencing a reversal of state (i.e., depressed or non-depressed) in the first extinction and then returned to the learning state on the second extinction. Results indicated that all groups learned in a comparable fashion. Experimental groups demonstrated no retention of the learned response on the first extinction, but extinguished normally on the second extinction when Ss were returned to the cortical state present during training. These results are consistent with an explanation of symmetrical dissociation. Control ~s which experienced the same state over all days demonstrated a predicted lack of dissociation. The theory of subcortical state specific retrieval was proposed to account for these data as well as results of studies reporting dissociation with other agents to relate dissociation phenomena to a single underlying process.
