Parkinson's disease is a degenerative central nervous system (CNS) condition characterized by progressive loss of cells within substantia  nigra. Substantia nigra is a portion of the midbrain, as illustrated in Figure, which is thought to be involved in certain aspects of movenient and attention. It consists of two subdivisions, the pars compacta and the pars reticlata. The cells within the substantia nigra release the neurotransmitter dopamine and it is the loss of dopamine that is primarily responsible for the motor defects.
