phasic

Occurring in cycles

Phasic describes something occurring in phases or relating to distinct stages.

In physiology, phasic refers to brief, rapid responses—a phasic muscle contraction is quick and temporary, contrasting with tonic (sustained) activity.

Phasic reflexes fire in bursts rather than continuously.

The term appears in neuroscience and psychology: phasic dopamine signals, phasic arousal.
