Abstract
Rats were poisoned 90 min after drinking a novel sucrose solution. Two or four days later, they were tested for learned aversions to sucrose while under the influence of various doses of scopolamine. In three replications, the evidence failed to indicate any substantial effect of scopolamine on retention of learned taste aversions. It is suggested that taste-aversion learning may be less dependent on changes in cholinergic synapses than are certain other types of learning.
