WebbThis video shows you how to pronounce Nigrostriatal WebbThe nigrostriatal pathway, or the nigrostriatal bundle (NSB), is a dopaminergic pathway that connects the substantia nigra with the dorsal striatum. It is one of the four major dopamine pathways in the brain, and is particularly involved in the production of movement, as part of a system called the basal ganglia motor loop.
The nigrostriatal pathway is a bilateral dopaminergic pathway in the brain that connects the substantia nigra pars compacta (SNc) in the midbrain with the dorsal striatum (i.e., the caudate nucleus and putamen) in the forebrain. It is one of the four major dopamine pathways in the brain, and is critical in … Visa mer The connection between the substantia nigra pars compacta and the dorsal striatum is mediated via dopaminergic axons.
