Summary Introduction
To review:
The way in which the signals carried by indirect or direct neurotransmitters are integrated by the postsynaptic neuron
Introduction:
The action potentials are generated in response to a stimulus. They travel from dendrites toward the cell body and then toward the axons. The axons conduct the action potential from the present neuron to the next neuron. The neurons that transmit the signals away from the cell body are called presynaptic neurons and those that receive the signals are called postsynaptic neurons. Synapse is the gap between the two neurons in which neurotransmitters are released.
