The connections between cholinergic nerve endings and nigrostriatal dopaminergic neurons were studied in the substantia nigra pars compacta of the human brain. Immunocytochemistry of tyrosine hydroxylase followed by ionic fixation of acetylcholine-like cation in synaptic vesicles allowed dopaminergic neurons and cholinergic nerve endings to be visualized on the same ultrathin section. Numerous ...
In this study, we investigated the effect of acupuncture at the Zusanli acupoint (ST36) on the nigrostriatal dopaminergic neuronal cell death in the rats with Parkinson's disease. Two weeks after unilateral injection of 6-hydroxydopamine (6-OHDA) into the striatum, an apomorphine-induced rotational behavior test showed significant rotational asymmetry in the rats with Parkinson's disease. Immun...
BACKGROUND Structural abnormality of the substantia nigra can be detected by transcranial sonography in neuropsychiatric disorders such as Parkinson disease and restless legs syndrome. We investigated echogenicity of the substantia nigra as a potential structural marker for dysfunction of the nigrostriatal dopamine system in children with attention-deficit hyperactivity disorder (ADHD). METHO...
Prior work has shown that functional connectivity between the midbrain and putamen is altered in patients with impairments in the dopamine system. This study examines whether individual differences in midbrain-striatal connectivity are proportional to the integrity of the dopamine system in patients with nigrostriatal dopamine loss (Parkinson's disease and dementia with Lewy bodies). We assesse...
