Slow wave potential

Webb11 mars 2024 · Some smooth muscles are self excitatory or spontaneously stimulated, showing what is called slow-wave potential, these waves if they reach the threshold value which is about -35 millivolts it fires an action potential, giving rise to muscle contraction. The cause of the slow-wave rhythm is unknown. Contractile process in smooth muscle WebbThere are several types of epileptiform activity, including single discharges (sharps and spikes) and rhythmic and/or periodic activity. It is important to note that the presence of epileptiform activity is not sufficient for a diagnosis of epilepsy in a …
