Synapses & Receptors Action Potential (AP) At rest, neural membranes have a negative resting membrane potential – why? AP is generated because of strong drive of Na+ to enter (influx) the neuron and terminated because of strong drive of K+ to exit (efflux) the neuron. Why? AP is “all or none” in nature (AP either occurs or it does not; e.g., you cannot have 1/2 of an AP) APs vary in frequency (a few spikes per second to a max of
