The substantia nigra (SN) is a basal ganglia structure located in the midbrain that plays an important role in reward and movement. Substantia nigra is Latin for "black substance", reflecting the fact that parts of the substantia nigra appear darker than neighboring areas due to high levels of neuromelanin in dopaminergic neurons .

The substantia nigra is a brain structure that is part of your basal ganglia. While it’s very small, this structure is essential in how your brain controls your body’s movements. It also plays a part in the chemical signaling in your brain, which affects learning, mood, judgment, decision-making and other processes.
Oct 24, 2022 · The substantia nigra (SN) is a midbrain dopaminergic nucleus which has a critical role in modulating motor movement and reward functions as part of the basal ganglia circuitry. Projections from the SN to the putamen, called the nigrostriatal pathway, are critically involved in the motor deficits observed in Parkinson disease.[1]
Oct 30, 2023 · The substantia nigra, also known as the black nucleus, is a large gray matter structure of the mesencephalon or midbrain (middle brain). It gets its name from its dark appearance on the cross-sections of the brain ( Latin for 'Black substance'). The dark coloration comes from the high number of neurons that contain the substance neuromelanin .
The substantia nigra (SN) is a small yet essential brain structure that plays a critical role in controlling your body's movements. By producing dopamine, the substantia nigra controls motor...
