[Representation of the visual pathways in the retrosplenial area of the rat limbic cortex]. 1983

R N Bilian

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.

UI	MeSH Term	Description	Entries
D008032	Limbic System	A set of forebrain structures common to all mammals that is defined functionally and anatomically. It is implicated in the higher integration of visceral, olfactory, and somatic information as well as homeostatic responses including fundamental survival behaviors (feeding, mating, emotion). For most authors, it includes the AMYGDALA; EPITHALAMUS; GYRUS CINGULI; hippocampal formation (see HIPPOCAMPUS); HYPOTHALAMUS; PARAHIPPOCAMPAL GYRUS; SEPTAL NUCLEI; anterior nuclear group of thalamus, and portions of the basal ganglia.
