(Source: BioGlossary, www.Biology-Text.com)[TAO] A ganglion is a cluster of neurons. It is part of a nervous system. It may include glial cells. The neurons are arranged in a specific constellation: neuronal somata are concentrated at the surface, thus forming a cell cortex, and neurites are concentrated in the centre of the ganglion to form the neuropil. A ganglion is a distinct unit but several ganglia may be anterio-posteriorly joined by connectives or transversally by commissures EHDAA:2897 EHDAA:5621 Cranial sensory placodes are focused areas of the head ectoderm of vertebrates that contribute to the development of the cranial sense organs and their associated ganglia. Placodes have long been considered a key character of vertebrates, and their evolution is proposed to have been essential for the evolution of an active predatory lifestyle by early vertebrates.[well established][VHOG] TODO - check vert vs invert.
