Neuron Physiology Notes
... Stages of a Nerve Impulse STAGE 1) Neuron at “resting membrane potential” is polarized with a resting potential of (-70 mv) 2.) Neuron is stimulated by the influx of a neurotransmitters that causes sodium channels to open. Sodium moves inward causing neuron to depolarize. (-62mv) 3.) Threshold is r ...
