(You can roll your mouse over the picture of the brain above to find out more about the parts of the brain.). Neurons. Every part of the brainâand the rest of the nervous system, for that matterâcontain neurons (more than 100 billion of them in all). Neurons are nerve cells with some very special properties.
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.
