[Convergence of activating connections of retinal on- and off-ganglion cells on lateral geniculate body neurons].
On- (off-) central neurons of the retina and lateral geniculate body (LGB) generate off- (on-) responses to stimuli acting upon the periphery of their receptive fields (RFs). We have found neurons with equal on- and off-responses to testing of the central part of their RFs. RFs of such neurons consist of overlapping on- and off-areas. The type of their responses can change on alteration of the stimulus parameters or under influence of light adaptation. A number of the LGB neurons seem to have activating inputs both from on- and off-central ganglionic cells of retina.
