The ability of rats with ibotenate lesions of the entorhinal cortex to form
memories for events was assessed by using a gustatory within-event learning
procedure. Rats first received exposure to 2 events, AX and BY, each composed of
a pair of flavors. Following this exposure period, Flavor X alone was paired with
the delivery of lithium chloride. Lesioned and control rats showed a greater
aversion to A than to B and to AX than to BX. These results challenge theories
that suppose that the entorhinal cortex plays a general role in forming
representations of patterns of stimulation.
