This neuron is characterised by Dogiel type II morphology (large smooth soma with multiple long axon-like processes), AH-type electrophysiology (prolonged afterhyperpolarization following an action potential), and is immunopositive for choline acetyltransferase (ChAT) and immunonegative for neuronal nitric oxide synthase (NOS1).
