By combining an observational spatial learning paradigm with a cerebellar lesion that blocks the acquisition of new spatial strategies it is possible to break up a complex spatial behavior into its fundamental units, in order to study which relations among units have to be maintained so that the behavior in toto might be acquired. Normal rats first observed companion rats performing single explorative behaviors (circling, extended searching, direct finding), then were hemicerebellectomized and finally tested in the maze. In spite of the cerebellar lesion, the observer animals displayed exploration abilities closely matching the previously observed behaviors. These results indicate that the single facets that form the strategy repertoire can be independently acquired.

Abstract
By combining an observational spatial learning paradigm with a cerebellar lesion that blocks the acquisition of new spatial strategies it is possible to break up a complex spatial behavior into its fundamental units, in order to study which relations among units have to be maintained so that the behavior in toto might be acquired. Normal rats first observed companion rats performing single explorative behaviors (circling, extended searching, direct finding), then were hemicerebellectomized and finally tested in the maze. In spite of the cerebellar lesion, the observer animals displayed exploration abilities closely matching the previously observed behaviors. These results indicate that the single facets that form the strategy repertoire can be independently acquired.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
