| Definitions |
Predominantly gray matter midbrain structure lying dorsal to the crus cerebri and ventral to the midbrain tegmentum. It is divided into a dorsal, cellularly compact region known as the pars compacta and a more ventrally located, containing more loosely packed cells, the pars reticulata. The most lateral region of the reticulata is identified as the pars lateralis (MM). |

| editor note |
TODO - In BTO and NIF, part of basal ganglion which is part of telencephalon - but this is inconsistent with being part of midbrain, if these are spatially disjoint, as in ABA |
