dopaminergic neurons definition
Dopaminergic neurons. The human brain contains approximately 400,000 to 600,000 dopaminergic neurons and thus make up less than 1% of the total number of brain neurons. There are nine dopamine-containing neuronal cell groups in the mammalian brain, each with distinct cellular properties.reater than 70% of all dopaminergic neurons are located in the substantia nigra (see Nigral dopaminergic Cell). Axons of dopaminergic neurons project to the brain by using one of three pathways: the mesostriatal, mesolimbic and mesocortical.
