Hyperpolarization
In
neuroscience,
hyperpolarization is the event a
neuron undergoes when its
membrane potential grows more negative with respect to the extracellular solution. Hyperpolarization can be caused by the flow of positively charged
ions (such as
potassium) out of the cell, or by the influx of negatively charged ions (such as
chloride). Compare to
depolarization.
