Abstract
Responses to visual stimulation were extracellularly recorded with micropipettes from 125 neurons of the left nucleus isthmi in frogs, R. nigromaculata, and 101 electrode tip positions were marked with Co staining. The entire contral ateral hemifield and the nasal 40.degree. of the ipsilateral hemifield project on the nucleus isthmi topographically. There are binocular units in this nucleus.
