Arousal measures accurately predicted multiple modes of membrane potential activity, including rhythmic slow oscillations at low arousal, stable hyperpolarization at intermediate arousal, and depolarization during phasic or tonic periods of hyper-arousal.
We then proceed in the 'The FitzHugh-Nagumo model' section with the FitzHugh-Nagumo equations in the case where the membrane potential equation includes noise.
The first represents the membrane potential and includes a cubic non-linearity, whilst the second variable is a gating variable, similar to w in the ML model, which may be thought of as a recovery variable.
However, both APD alternans and SDs result from a complex interaction between membrane potential, ion currents including ICaL and INa/Ca, and Ca2+i cycling, each of which may be altered by myocardial disease as well as stimulation rate.
A four-state ECC model was shown to produce the amplitude and the frequency windows of the Rb-pumping if the free energy of interaction of the transporter with the membrane potential was to include a nonlinear quadratic term.
However, potential differences in the intrinsic electrophysiological properties of Purkinje neurons, including membrane potential and action potential firing rates, have not been investigated.
Although the sustained VT can be a life-threatening arrhythmia and may easily lead to ventricular fibrillation and sudden death, the cellular activities, including membrane potential and Ca2+ dynamics, are not well known.
Ion transport controls several crucial physiological parameters, including membrane potential and ion balance [ 64].
PZA clearly interferes with multiple targets in M. tuberculosis, with activities including membrane potential disruption, internal pH acidification, and trans-translation inhibition.
