The rapid habituation of many neurons in the frog optic tectum to moving spots is presumed to underlie the behavioral habituation of the frog to repeated movement of prey objects. The "disinhibited" feeding of frogs after pretectal lesions is paralleled by the consistent failure of tectal neurons to ignore moving buglike stimuli.
