Slow wave threshold

Slow wave threshold

In neurobiology, the slow wave threshold is the potential which must be reached before a slow wave can be propagated in smooth muscle. Slow waves cause no smooth muscle contraction.

Gastrointestinal Smooth Muscle

In gastrointestinal smooth muscle, the slow wave threshold can be altered by input from endogenous and exogenous innervation, as well as excitatory (acetylcholine and Substance P) and inhibitory (vasoactive intestinal peptide and nitric oxide) compounds.
