Dopamine – CNS Pathways and Neurophysiology

The firing rates of DA neurons fall into a fairly limited range, usually 2–8 Hz, which consequently might limit the flexibility of DA neurons to release differential amounts of DA in terminal regions. However, this is overcome by a change in firing pattern from singlespike firing to burst firing. Bu ...
