Abstract

We applied tests of antidromic activation to identify cells in the hamster intergeniculate leaflet (IGL) that project to either the suprachiasmatic nucleus (SCN) or the contralateral IGL. IGL cells projecting to these targets were tested for photic responses; most showed sustained activation, while a few were suppressed by retinal illumination. Stimulation of one IGL typically suppressed firing in contralateral IGL cells and inhibited responses to immediately succeeding photic stimulation.
