[phasic neuron]
This term refers to the electrophysiological behaviour of neurons and describes one way in which action potentials are emitted from these cells.

For a type of neuron with some kind of hybrid response see also: Phasic-tonic cells.
The term phasic ganglion cells has been used to describe one of two broad categories of primate retinal ganglion cells (Gouras, 1968) (see also: tonic ganglion cells
