The substantia nigra (Japanese reading: kokushitsu; substantia nigra = Latin for “black substance”) is a nucleus occupying part of the midbrain. It is broadly divided into 2 groups, the pars compacta and pars reticulata (and pars lateralis), both central components of the basal ganglia. Coronal section passing through the superior colliculus. The dark gray area is the substantia nigra.
Dopamine is produced in a tissue called the substantia nigra in the midbrain. Dopaminergic neurons in the substantia nigra extend projections to the striatum and release dopamine from their tips (synapses). Sufficient dopamine is produced, and movement commands are transmitted. Dopamine is insufficient, and movement commands are not transmitted properly.

黒質（こくしつ、substantia nigra = ラテン語で「黒い物質」の意）は中脳の一部を占める神経核である。 黒質は、緻密部と、網様部（および外側部）とによって、大きく二群に大別されるが、いずれも大脳基底核を構成する中心的な要素である。 上丘を通過する冠状断面。 濃い灰色の所が黒質。
ドパミンは中脳にある黒質という組織でつくられています。 黒質のドパミン神経細胞は、線条体という部分に突起を伸ばして、この突起の先（シナプス）からドパミンを放出します。 ドパミンが充分つくられ、運動の命令が伝わっている。 ドパミンが不足して、運動の命令がうまく伝わらない。
