A '''dopaminergic nerve fibre''' is a [[nerve fibre]] for which the [[neurotransmitter]] is [[dopamine]]; that is to say, it is triggered into firing when incident nerves that form a [[synapse]] with it releases dopamine into the [[synaptic cleft]].
Dopaminergic nerve terminals are present in many [[brain]] nuclei, and are particularly associated with those that control [[emotion]]al and [[motivation]]al behaviour, as well as the control of movement. Disorders in the dopaminergic neurons of the [[substantia nigra]] in the [[basal ganglia]] of the brain are known to result in [[Parkinson's Disease]].
Dopaminergic nerve terminals contain a number of uptake mechanisms for the transmitters that are released into the synaptic cleft. These uptake mechanisms are the target for numerous drugs.
