Central Nervous System Onard Mejino There's an issue on the question of the retina. There's contention about this issue. Jyl: From e-mail discussion on retina, the consensus seemed to be that cranial nerves (I and 2) (retina and bulbus olfactorius) are part of sensory organs that are part of CNS, while cranial nerves III-XII are considered part of the PNS, as are spinal nerves.

In vertebrates it consists of the brain, spinal cord and **spinal nerves**. In those invertebrates with a central nervous system it typically consists of a brain, cerebral ganglia and a nerve cord Maryann Martone "commonality of cytoarchitecture, chemoarchitecturel" how to capture that.

Onard: How do we distinguish ganglion with nucleus. Is the only differentia location? Functionally differetia? "discrete aggregate of neuron bodies". Note that the basal ganglion is not a ganglion in this sense.

Gray matter Part of neuraxis in which cell bodies and unmyelinated nerve processes predominate giving it a pinkish gray appearance in gross preparations, e.g., thalamic nucleus Comments: Issue 1. Scope? - Nucleus of Neuraxis, of Spinal cord, of Brain. "direct part" in FMA is an issue. Most granular part for an object. Subcortical needs to be defined. Maybe not in the scope of CUMBO because it references cortex. Subcortical = part of the cerebral hemisphere but not part of the cortex. "sub" is not locational in this case it is functional. Onard: Medullary part. Maryanne - need to clarify the scope. "cytoarchitecture" correlates with "discrete aggregate of neuronal soma". See definition of CARO tissue for discussion related to cytoarchitecture and chemoarchitecture. FMA: Nucleus of brain is a subcortical gray matter which has as its direct proper parts predominantly discrete aggregate of somas of neurons. Group of cells that have commonality of cytoarchitecture chemoarchitecture and connections A subcortical part of the nervous system consisting of a relatively compact group of cells that is distinguishable histologically that share a commonality of cytoarchitecture, chemoarchitecturel and connectivity. (comments: I put in "subcortical" because I don't think we consider either the cerebellar cortex or cerebral cortex to be nuclei. Some people distinguish between a nucleus and a laminar structure (see Wikipedia definition). However, there are structures identified as nuclei that are laminar, e.g., lateral geniculate nucleus, although they are not laminated in all species. Also, I put in "relatively compact" and "distiguishable by histology" because we have groups of cells, e.g., cholinergic cell groups, doparminergic cell groups that are related on the 3 criteria but which we don't tend to consider nuclei because they don't occupy an easily defined territory.
