Why do neurons have a negative resting potential? What is the nature of an action potential? A synaptic potential? What allows an action potential to be propagated along an axon (for many centimeters)? Why are synaptic potentials NOT propagated? How does one neuron excite (depolarize) or inhibit (hyperpolarize) another neuron? What is responsible for the 0.5 msec delay at the synapse? How do neurons “know”which other neurons to synapse
