Oct 24, 2022 · Located within the midbrain posterior to the crus cerebri fibers of the cerebral peduncle, the substantia nigra can be functionally and morphologically divided into two regions, the pars compacta (SNpc) containing dopaminergic neurons and the pars reticulata (SNpr) with inhibitor gamma-aminobutyric acid-containing (or GABAergic) neurons (see .
Oct 30, 2023 · The substantia nigra is a paired structure of the midbrain. More specifically, it is located posterior to the crus cerebri. Based on its structure and function, the substantia nigra can be divided into two functionally independent areas: Pars compacta; Pars reticulata; Pars compacta

Oct 4, 2022 · The substantia nigra location is between the midbrain and the diencephalon, a brain structure that connects the midbrain to the forebrain. Conventionally, the substantia nigra is...
Dec 8, 2023 · The Substantia Nigra, Latin for “black substance,” is aptly named for its dark coloration, a result of high levels of neuromelanin in dopaminergic neurons. This structure is situated in the midbrain, an area that connects the forebrain and hindbrain, playing a pivotal role in motor control and a host of other functions.
Aug 21, 2017 · SN neurons can be divided into three tiers based on their staining, morphology, and connectivity with the striatum ( Haber, 2014; Haber and Knutson, 2010 ): moving from a dorso-medial to ventro-lateral location in midbrain, dopamine neurons project to limbic, associative and then motor striatum.
Quick Facts. The substantia nigra is located in the midbrain and plays an important role in reward, addiction and movement. The substantia nigra appears darker than neighboring areas, due to high levels of melanin in dopaminergic neurons. Parkinson's disease is characterized by the death of dopaminergic neurons in the substantia nigra.
