  1. Nov 08, 2020 · 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] These dopaminergic neural projections leave the SN via the medial ...

  2. 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.

  3. The VTA and substantia nigra (SN) comprise two major subregions of the ventral midbrain (VM). Although originally perceived as a dopaminergic structure, the VTA is in fact a heterogeneous region consisting of DA (~ 65%), GABA (30%), and glutamate neurons (~ 5%) [19,33–36].

  4. Nov 15, 2014 · The substantia nigra is a region in the midbrain that is considered part of the basal ganglia. It looks like a darkened streak in unstained brain tissue; this is where it gets its name, which is Latin for "black substance." Although it is often referred to as one structure, there are actually two substantia nigrae, one on each side of the ...

  5. Nov 25, 2020 · Substantia nigra is a large motor nucleus present in the midbrain. It is a part of brain stem and is present in the cerebellar peduncles of midbrain. Structurally, it is present in midbrain, but. functionally; it is considered to be a part of basal ganglia. Substantia nigra comprises of two structural.

  6. 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 obs …

  7. The substantia nigra plays a role in the process of addiction. The substania nigra is an area of pigmented cells in the midbrain which is responsible for producing the neurotransmitter dopamine. This section of the brain plays an important role in the control of movement, and it also appears to interact in the process of addiction, as well.
