Definitions:

Continuous Conduction

The propagation of an electrical impulse along an unmyelinated axon without interruption.

Action Potentials

Rapid, temporary changes in the electrical membrane potential of a cell, which allow for the transmission of signals along neurons.

Local Currents

Electrical currents that flow in the neuronal membrane due to the movement of ions in and out of the neuron, vital for the propagation of action potentials.

Absolute Refractory Period

A time period during which a neuron cannot fire another action potential, no matter how strong the stimulus.
