Anatomical terms of neuroanatomy

The pars compacta (SNpc) is one of two subdivisions of the substantia nigra of the midbrain (the other being the pars reticulata); it is situated medial to the pars reticulata. It is formed by dopaminergic neurons.[1] It projects to the striatum and portions of the cerebral cortex.[2] It is functionally involved in fine motor control.

Parkinson's disease is characterized by the death of dopaminergic neurons in this region.[1]
