What is Substantia Nigra

The substantia nigra is a region of the brain which contains neurons that produce the neurotransmitter dopamine. It is black in appearance, giving rise to the name ("substantia nigra" is Latin for "black substance".)

Substantia Nigra Function

Neurons in the substantia nigra travel to brain areas which are important for motor control as well as to the frontal lobes, which are important for attention and executive function. Parkinson's disease is a disorder that involves progressive death of neurons in the substantia nigra, leading to motor and cognitive symptoms.
