It is important to understand the ways in which the electric potentials travel through the neurons, because the electric signals are what enables the neurons to communicate with each other thereby creating the informational network that transmits the information from sensory neuron the motor neuron. To understand the electric potentials and the sodium potassium pump and the concentration gradiates is to understand one aspect of neuron action. What interests me now is how axons and dendrites communicate through the synaptic cleft and how the electric impulses interact with neurotransmitters.

Fair enough. Will get to most of that. PG
