Septal-hippocampal system lesions, mostly using aspiration techniques, have been reported to impair performance of conditional tasks. Rats with axon-sparing cytotoxic hippocampal lesions were therefore tested in a range of instrumental conditional paradigms. They did not differ from controls in their ability to choose the appropriate object in a conditional object discrimination cued by internal state (hunger or thirst) or on performance of conditional visuospatial object discriminations.
