WebHyperpolarization (biology) Hyperpolarization is any change in a cell's membrane potential that makes it more polarized. That is, hyperpolarization is an increase in the absolute value of a cell's membrane potential. Thus, any change of membrane voltage in which the membrane potential moves farther from zero, in either a positive or negative ... WebWe suggest a biologically plausible switching mechanism between the possible bursting patterns by application of a small hyperpolarized current that temporarily blocks a targeted cell. Mutant channels were activated and reached maximal current amplitude at more hyperpolarized potential as compared with wild type channel.
