Summary Introduction

To review:

The mechanism by which action potentials of a postsynaptic neuron are regulated by the ionotropic receptor bound neurotransmitter in the presynaptic neuron.

Introduction:

Action potentials travel from dendrites toward the cell body or axons. Axons conduct the action potential toward dendrites of the next neuron. The neuron that transmits the signals are called presynaptic neurons and those that receive the signals are called postsynaptic neurons. Synapse is the gap between two neurons in which neurotransmitters are released.
