| has gloss | (noun) a layer of deeply pigmented grey matter in the midbrain; associated with the striate body; is involved in metabolic disturbances associated with Parkinson's disease and with Huntington's disease locus niger, nucleus niger, substantia nigra |
| has gloss | eng: The substantia nigra is a brain structure located in the mesencephalon (midbrain) that plays an important role in reward, addiction, and movement. Substantia nigra is Latin for "black substance", as parts of the substantia nigra appear darker than neighboring areas due to high levels of melanin in dopaminergic neurons. The substantia nigra is part of the basal ganglia; the other parts of the basal ganglia include the striatum (caudate nucleus, putamen, and nucleus accumbens), globus pallidus, and subthalamic nucleus. Parkinson's disease is caused by the death of dopaminergic neurons in the substantia nigra pars compacta. |

Son nom provient de la couleur des cellules qui composent ce noyau en raison de la présence de neuromélanine. |

| has gloss | nld: De substantia nigra (zwarte substantie), vroeger ook wel zwarte kern genoemd, is een pigmenthoudende kern in het mesencephalon, ofwel het middendeel van de hersenen. Het behoort tot de basale kernen ofwel basale ganglia van het zenuwstelsel. (Het overige deel van de basale ganglia wordt gevormd door het corpus striatum, de globus pallidus en de nucleus subthalamicus. De substantia nigra bevat twee deelstructuren, de pars reticulata (SNr) en de pars compacta (SNc). De substantia nigra (vooral de SNc) heeft een dopaminerge projectie op het putamen en de hersenschors. |

Den består av to markant forskjellige områder, pars compacta og tilligende områder med dopaminerge nevroner, og en annen gruppe som utgjøres av pars reticulata og pars lateralis. Den siste gruppen, sammen med nucleus pallidus utgjør kjernen i basalgangliene. Selv om anatomien er intrikat og knyttet til hverander, er de to gruppene anatomisk og funksjonelt adskillelige. |
