The pars compacta (SNpc, SNc) 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. It projects to the striatum and portions of the cerebral cortex. It is functionally involved in fine motor control.
Parkinson's disease is characterized by the death of dopaminergic neurons in this region.
