The Action Potential - видео

In this video Paul Andersen details the action potential in neurons. The resting potential of a neuron -70mV is maintained through differences in concentration and permeability of Na K and Cl ions. A graded potential is created as neurotransmitters from adjacent cells that are either excitatory or inhibitory. If the neuron reaches the threshold of -55mV an opening of voltage-gated sodium channels triggers an action potential that may affect other connected neurons. PhET neuron simulation - M...
