NONSPATIAL LEARNING FOLLOWING POSTERIOR PARIETAL OR HIPPOCAMPAL-LESIONS

POSTERIOR parietal, hippocampal, or sham-lesioned rats were tested for the acquisition of a non-monotonic serial learning task. The performa nce of control rats and those with a posterior parietal lesion was sim ilar, while those with hippocampal damage demonstrated a working memor y deficit. The results are integrated with contemporary conceptualizat ions of hippocampal and posterior parietal cortex involvement in learn ing and memory for nonspatial tasks.
