[Representation of the visual pathways in the retrosplenial area of the rat limbic cortex].
Visual inputs to field 29 of the limbic retrosplenial cortex have been studied by means of paired stimuli, i.e. photic and electrical stimulation of the anterodorsal nucleus (ADN). During stimulation of this nucleus, the evoked potentials in the field 29 decreased in the initial phase of visual stimulation, indicating the involvement of the ADN into the visual system. This finding confirms earlier morphological data [2]. Besides this, in the field 29 neurones were found which responded to light but not to ADN stimulation, suggesting the possibility of termination of different visual inputs on the neurones of the limbic cortex.
