Visual sensitivity of optic tectum-ablated goldfish was investigated using a classical conditioning technique. Intact fish were screened to obtain individuals which showed suppression of breathing movements in response to the visual conditioned stimulus (CS) in the presence or absence of adapting illumination. Following bilateral optic tectum ablation, responding was blocked in light-adapted but not dark-adapted fish. Response threshold testing revealed no significant postoperative changes in visual sensitivity. Small remnants of tectal tissue containing cellular elements of the periventricular gray zone and optic axon terminals were detected in some ablates but there was no evident relationship to response threshold. Optic nerve crush bloc...
