Different Types of Synapses There are two main types of synapses: Chemical Synapse: The first is the chemical synapse in with the electrical activity in the presynaptic neuron triggers the release of chemical messengers, the neurotransmitters. The neurotransmitters diffuse across the synapse and bind to the specialized receptors of the postsynaptic cell. The neurotransmitter then either excites or inhibits the postsynaptic neuron. Excitation leads to the firing of an action potential while inhibition prevents the propagation of a signal.
