Following binding of the neurotransmitter with a receptor, the postsynaptic membrane depolarizes which results in the generation of an impulse on the next neuron or the effector cell, e.g., muscle cell or secretory cell.

This depolarizes a critical mass of the heart muscle, terminates the arrhythmia, and allows normal sinus rhythm to be reestablished by the body's natural pacemaker, in the sinoatrial node of the heart.

This ~63-kDa band also increases in the mitochondria-rich membrane fraction following treatment with valinomycin, which, unlike CCCP, depolarizes mitochondria by permeabilizing the membrane to K PINK1 selectively accumulates on depolarized mitochondria.

This possibility notwithstanding, even if in studies investigating tDCS-induced changes in primary cortices anodal stimulation delivered close to neurons depolarizes the neuronal membrane and cathodal stimulation hyperpolarizes it, cognitive studies leave the relation between polarity and the effects on the neuronal membrane unclear

We have recently shown evidence that reduced sensitivity of ort6 receptors depolarizes LMCs and possibly ACs, and that this artificially high membrane potential enhances their excitatory synaptic feedbacks to the photoreceptor terminals
