Abstract
Animals with hippocampal lesions are evaluated as models for schizophrenia according to the criteria of McKinney and Bunney (1969). They seem to comply adequately with the following requirements: (1) similarity of inducing conditions; (2) similarity of behavioral states; (3) similarity of underlying neurobiological mechanisms; and (4) reversibility by usual pharmacological treatment. The model seems adequate to reproduce several symptoms of the disorder, offering a good experimental tool for the analysis of its inducing conditions, affected neurobiological mechanisms, and clinical treatment.
