A '''phase response curve''' ('''PRC''') illustrates the transient change ([[phase response]]) in the cycle period of an [[Simple harmonic motion|oscillation]] induced by a perturbation as a function of the [[phase (waves)|phase]] at which it is received.  PRCs are used in various fields; examples of biological oscillations are the heartbeat, [[circadian rhythm]]s, and the regular, repetitive firing observed in some neurons in the absence of noise.<ref>{{cite journal | vauthors = Canavier CC |title=Phase response curve |journal=Scholarpedia |volume=1 |issue=12 |page=1332 |date=2006 |doi=10.4249/scholarpedia.1332|bibcode=2006SchpJ...1.1332C |doi-access=free }}</ref>{{Better source needed|reason=Scholarpedia fails [[WP:UGC]].|date=January 2019}}
