The Effect of Post-Conditioning Exposure to Morphine On the Retention of a Morphine-Induced Conditioned Taste Aversion
In the following experiment, multiple injections of morphine sulfate following the acquisition of a morphine-induced taste aversion had no effect on the retention of the previously acquired aversion. Post-conditioning injections of morphine resulted in the development of physical dependence to morphine and led to a decrement in the ability of morphine to induce a subsequent aversion to a second novel taste. This failure of post-conditioning exposures to morphine to affect a previously acquired morphine-induced taste aversion even though tolerance to morphine had occured was discussed in the context of Rescorla's event-memory model of conditioning.
