Definition that contains grey matter
- cortex the layer of unmyelinated neurons (the grey matter) forming the cortex of the cerebrum
- hippocampus a complex neural structure (shaped like a sea horse) consisting of grey matter and located on the floor of each lateral ventricle; intimately involved in motivation and emotion as part of the limbic system; has a central role in the formation of memories
- thalamus large egg-shaped structures of grey matter that form the dorsal subdivision of the diencephalon
- striatum a striped mass of white and grey matter located in front of the thalamus in each cerebral hemisphere; consists of the caudate nucleus and the lenticular nucleus
- golgi's cell a neuron in the cerebral cortex with short dendrites and with either a long axon or a short axon that ramifies in the grey matter
- neuropile the complex network of unmyelinated axones, dendrites, and glial branches that form the bulk of the central nervous system's grey matter and in which nerve cell bodies are embedded
- basal ganglion any of several masses of subcortical grey matter at the base of each cerebral hemisphere that seem to be involved in the regulation of voluntary movement
- corpus striatum a striped mass of white and grey matter located in front of the thalamus in each cerebral hemisphere; consists of the caudate nucleus and the lenticular nucleus
- locus niger a layer of deeply pigmented grey matter in the midbrain; associated with the striate body; is involved in metabolic disturbances associated with Parkinson's disease and with Huntington's disease
- nucleus niger a layer of deeply pigmented grey matter in the midbrain; associated with the striate body; is involved in metabolic disturbances associated with Parkinson's disease and with Huntington's disease
