Ganglion cells of the cat accessory optic system: morphology and retinal topography. 1982

S G Farmer, and R W Rodieck

The ganglion cells of the cat's retina form classes that are distinct in their cell morphology, retinal distribution, central projections, and functional properties. By means of the retrograde transport of horseradish peroxidase injected into the accessory optic nuclei of the cat midbrain, we have characterized the retinal ganglion cells projecting to these nuclei. The retinal projection is virtually completely crossed to the medial terminal nucleus and to the lateral terminal nucleus. This appears to be true for the dorsal terminal nucleus as well, although difficulties of the technique limit our findings for this region. No differences were found in either the spatial distribution, or the somal size distribution, or the morphological characteristics of the ganglion cells projecting to these three nuclei. In spatial distribution, these cells are concentrated in the area centralis and visual streak and show no evidence of a nasotemporal division. Morphologically, they have small to medium-sized somas and delicate, sparsely branching dendrites. They do not appear to belong to any of the morphological cell type thus far identified.

UI	MeSH Term	Description	Entries
D008636	Mesencephalon	The middle of the three primitive cerebral vesicles of the embryonic brain. Without further subdivision, midbrain develops into a short, constricted portion connecting the PONS and the DIENCEPHALON. Midbrain contains two major parts, the dorsal TECTUM MESENCEPHALI and the ventral TEGMENTUM MESENCEPHALI, housing components of auditory, visual, and other sensorimoter systems.

D009474	Neurons	The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.	Nerve Cells,Cell, Nerve,Cells, Nerve,Nerve Cell,Neuron
D012160	Retina	The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.	Ora Serrata
D001931	Brain Mapping	Imaging techniques used to colocalize sites of brain functions or physiological activity with brain structures.

D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D004594	Electrophysiology	The study of the generation and behavior of electrical charges in living organisms particularly the nervous system and the effects of electricity on living organisms.
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
