Receptive field properties of rat ventral lateral geniculate cells projections to the superior colliculus

Cells of the ventral lateral geniculate nucleus (LGV) in rats sending their axons to the superior colliculus (SC), were identified electrophysiologically as the ones responding antidromically to electrical stimulation of SC. They were located in the external part of LGV. Visual receptive fields of these cells were mostly of ON-tonic types and some of the movement-sensitive ones. Evidence was presented supporting existence of the reciprocal fiber connection between the LGV and the SC.
