May 15, 2022 · The substantia nigra (sub-stan-chee-uh ny-grah) is a part of your basal ganglia, forming connections with different parts of your brain. It produces dopamine, which controls movements and muscle tone. The substantia nigra has two different sections, and they both have different roles and connections. The two sections are:
Oct 24, 2022 · USA.gov. 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 (see Illustrations. Substantia Nigra and The Basal Ganglia Circuitry and its Associated Motor, Cognitive, and Limbic Uutputs).

Oct 30, 2023 · Being one of the main sources of dopamine in the brain and a crucial part of the basal ganglia pathways, the prime function of the substantia nigra is in the initiation and control of movement. Movement is controlled in the basal ganglia loop via a direct pathway and an indirect inhibitory pathway.

Oct 30, 2023 · The basal ganglia consist of five pairs of nuclei: caudate nucleus, putamen, globus pallidus, subthalamic nucleus, and substantia nigra. These nuclei are grouped into broader clusters; Striatum, which further consists of the: Dorsal striatum, made by the caudate nucleus and putamen.

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.

Jul 24, 2023 · The largest component of the basal ganglia is the corpus striatum which contains the caudate and lenticular nuclei (the putamen, globus pallidus externus, and internus), the subthalamic nucleus (STN), and the substantia nigra (SN).
The term basal ganglia in the strictest sense refers to nuclei embedded deep in the brain hemispheres (striatum or caudate-putamen and globus pallidus), whereas related nuclei consist of structures located in the diencephalon (subthalamic nucleus), mesencephalon (substantia nigra), and pons (pedunculopontine nucleus).
