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
- pallium the layer of unmyelinated neurons (the grey matter) forming the cortex of the cerebrum
- 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
- cerebral cortex the layer of unmyelinated neurons (the grey matter) forming the cortex of the cerebrum
- cerebral mantle the layer of unmyelinated neurons (the grey matter) forming the cortex of the cerebrum
- claustrum a layer of grey matter in the brain adjacent to the lenticular nucleus
- 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
