Most of the time, a presynaptic neuron does not only affect one postsynaptic neuron. The axon terminals usually attach to many other neurons. A single neuron will only release one neurotransmitter. However, because the proteins in the membrane of the postsynaptic neuron determines whether they will stimulated or inhibited, a single presynaptic neuron can inhibit one cell and stimulate another. Likewise, a postsynaptic neuron is usually affected by more than one presynaptic neuron. If different presynaptic neurons release different neurotransmitters, the combined affects of the stimuli and inhibition may cancel each other out. In addition, usually, one presynaptic axon terminal cannot stimulate a postsynaptic neuron enough to reach threshold by itself. If many of them stimulate the postsynaptic neuron at the same time without too many inhibiting the postsynaptic neuron, then threshold may be reached.

False. They can receive messages from up to five different presynaptic neurons at a time.
