==Action upon other neurones==
==Action upon other neurones==
A neurone affects other neurones by releasing a [[neurotransmitter]] that binds to chemical [[receptor|receptors]]. The effect upon the postsynaptic neurone is determined not by the presynaptic neurone or by the neurotransmitter, but by the type of receptor that is activated. Receptors can be classified broadly as [[Neurotransmitter#Excitatory and Inhibitory Effects|excitatory]] (causing an increase in firing rate), [[Neurotransmitter#Excitatory and Inhibitory Effects|inhibitory]] (causing a decrease in firing rate), or modulatory (causing long-lasting effects not directly related to firing rate). The distinction between excitatory and inhibitory neurotransmitters is not absolute, however. Rather, it depends on the class of chemical receptors present on the postsynaptic neurone. In principle, a single neurone, releasing a single neurotransmitter, can have excitatory effects on some targets, inhibitory effects on others, and modulatory effects on others still.
