Definition
Dopaminergic (DA) neurons are defined as neurons synthesizing and containing the neurotransmitter and neurohormone dopamine. Such neurons release dopamine synaptically as well as dendritically (Bustos et al. 2004).
The electrophysiological signatures of this neuron are broad action potentials (Fig. 1) and a low-frequency, regular spontaneous activity (Fig. 2a).
A distinctive property of the DA neuron is that it differentially responds to different types of excitatory synaptic inputs (Fig. 2a, b).
Models have explained these properties and connected them with one another and with particular current compositions (Figs. 3 and 4).
