The membrane potential of the neuron has a negative resting or equilibrium value is called ____________(a) Hyperpolarization(b) polarization(c) Hypolarization(d) HypopolarizationI got this question in an online interview.My doubt is from Neural Networks topic in portion Distributions, Graphics & Neural Networks of R Programming

Answer»

Correct OPTION is (a) HYPERPOLARIZATION

To elaborate: The MEMBRANE potential of the NEURON has a negative RESTING or equilibrium value. Making this more negative leads to a hyperpolarization which are trying to depolarize the membrane.
