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
- 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
- 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
- cerebral cortex the layer of unmyelinated neurons (the grey matter) forming the cortex of the cerebrum
- substantia nigra 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
- dentate nucleus a large laminar nucleus of grey matter within the white matter of each cerebral hemisphere
- pallium the layer of unmyelinated neurons (the grey matter) forming the cortex of the cerebrum
