[Study of the afferent connections of the visual area of the lower bank of the cruciate sulcus of the cerebral cortex of the cat using the retrograde horseradish peroxidase axon transport technic].
The possible visual inputs to the new visual area found in our experiments in the lower bank of cruciate sulcus of the cat cortex were studied with horseradish peroxidase technique. HRP was injected in the place preliminary identified as the visual area in physiological experiments with the same cats. Labelled neurons were found in the visual areas of the cortex (lateral suprasylvian and ectosylvian), in the parietal cortex (area 5 and 7) and in a small amount in the prefrontal and limbic cortex. In all experiments labelled neurons were found in the claustrum. In the thalamus labelled neurons were found in the nucleus medialis dorsalis, intralaminar nuclei (contralis lateralis, paracentralis and centralis medialis) and in the nuclei ventralis anterior, ventralis medialis, anteromedialis and reuniens. Some stained neurons were found in the midbrain in the stratum griseum centrale; the conclusion was made that the main sources of inputs to the studied area were different regions of the visual system or the structures of the brain closely connected with the latter.
