Unformatted text preview: • Define temporal and spatial summation and understand how they can influence the likelihood that a neuron will fire an action potential • Explain how the movement of ions contributes to the generation and propagation of the action potential • Explain why action potentials usually only travel in one direction Lecture 3 Objectives • Explain the ionic basis for the refractory period. Compare absolute versus relative refractory period in terms of the likelihood a neuron will fire • Describe what is meant by the action potential being All-or-None and being nondecrimental in its propagation • Describe the 2 factors contributing to the velocity of the action potential...
