Ciprofloxacin is an antibacterial prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment and prevention of certain bacterial infections, including: Urinary tract infections. Lower respiratory tract infections.
In neurophysiology Hyperpolarization is a change in a cell's membrane potential that makes it more negative. It is the opposite of a depolarization.Hyperpolarization is often caused by efflux of K+ (a cation) through K+ channels, or influx of Clâ (an anion) through Clâ channels. On the other hand, influx of cations, e.g. Na+ through Na+ channels or Ca2+ through Ca2+ channels, inhibits hyperpolarization.t is the opposite of a depolarization.

hyperpolarization. A change in the value of the resting membrane potential towards a more negative value. The inside of the cell becomes more negative than the outside.Hyperpolarization is inhibitory because the membrane potential moves away from the neuron's threshold at which an action potential could occur.Example: the retinal photoreceptor potentials when stimulated by light.
