An area of the brain which degenerates in<unk> 's disease, called the substantia nigra pars compacta, is visualized as two dark brown bands in the lower half of the image.<unk>  include various investigational procedures which transplant specific populations of<unk> s into the brains of people with<unk> 's disease. The investigation of<unk>  transplantation<unk>  followed the discovery that the death of dopaminergic neurons in the substantia nigra pars compacta resulted in the motor symptoms of the disease.
