Post-mortem staining of the brain slices showed atrophy of the substantia nigra
As a novel neuroimaging technology, transcranial sonography (TCS) of PD patients reveals characteristic substantia nigra
(SN) hyperechogenicity, which may be related to iron accumulation and functional impairment of nigrostriatal pathways.
For ethical reasons, researchers cannot take cells from the substantia nigra
to study them.
Increased frequency of [alpha]-synuclein in the substantia nigra
in HIV infection.
And because the substantia nigra
is awash in both dopamine and iron, neurons there may be exposed to an extra-large dose of 6-hydroxydopamine.
BRAIN There are opioid receptors throughout the brain, including in the cerebral cortex, cerebellum, nucleus accumbens, ventral tegmental area, substantia nigra
, and hypothalamus of the brain.
9) may indicate neuronal loss, but substantia nigra
appears normal in most PD patients.
Progressive impairment of voluntary motor control, which represents the primary clinical feature of the disease, is caused by a loss of midbrain substantia nigra
dopamine (DA) neurons.

Parkinson's is caused by a loss of nerve cells in part of the brain called the substantia nigra
It works as a messenger that transfers signals in an area in the brain called the substantia nigra
to produce smooth, controlled movements.
Metabotropic glutamate receptors (mGluRs) are G-protein coupled receptors that contain the binding site for glutamate, and mGlu4, specifically, is localized to presynaptic terminals in a region of the brain called the substantia nigra
pars compacta (SNpc).
The substantia nigra
is the part of the brain affected in Parkinson's disease.
Changes in vascularization in substantia nigra
pars compacta of monkeys rendered parkinsonian.
Most notable were the substantia nigra
and the nucleus locus coeruleus.
