It is the process by which signalling molecules called neurotransmitters are released by the axon terminal of a neuron (the presynaptic neuron) and bind to and react with the receptors on the dendrites of another neuron (the postsynaptic neuron). Neurotransmission is usually faster than neuromodulation, and is more likely to be ionotropic, while neuromodulation is slower and more likely to be metabotropic. Neurotransmission relies upon: the availability of the neurotransmitter; the release of the neurotransmitter; the connection made between the postsynaptic receptor by the neurotransmitter; activity from the postsynaptic cell; and the subsequent removal or deactivation of the neurotransmitter.
