The substantia nigra is susceptible to compression by an increase in CSF volume in the cisterns and cerebral aqueduct.

The substantia nigra is susceptible to compression by an increase in CSF volume in the cisterns and cerebral aqueduct.

The substantia nigra is a brain structure located in the mesencephalon that plays an important role in reward, addiction, 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.[1] It was discovered in 1784 by Félix Vicq-d'Azyr,[2] and Samuel Thomas von Sömmerring alluded to this structure in 1791.[3] Parkinson's disease is…

The basal ganglia are masses of nuclei, of gray matter found deep in the brain which are involved in the control of movement sequences such as in walking. It is made up of the globus pallidus, caudate nucleus, putamen, substantia nigra, and subthalamic nuclei.

MRI Technique Could Help Track How Parkinson’s Patients Respond to Treatment: Image: MIT neuroscientists imaged the substantia nigra in a young adult, left, an older adult, center, and a Parkinson’s patient, right. They found that the substantia nigra deteriorates in Parkinson’s patients (Photo courtesy of David Ziegler).

The loci of the major cell groups and fiber tracts at the level of the midbrain. IC = inferior colliculus; LC = locus ceruleus; MLF = medial longitudinal fasciculus; Mes V = mesencephalic nucleus of cranial nerve (CN) V; MO V = motor nucleus of CN V; MO VII = motor nucleus of CN VII; RN = red nucleus; SC = superior colliculus; SN = substantia nigra; VI = nucleus of CN VI; IV = nucleus of CN IV; III = nucleus of CN III.
