In Neurophysiology, inhibition is the effect of one neuron upon another tending to prevent it from initiating impulses. At cellular level, there are 3 modes of inhibition: postsynaptic inhibition, presynaptic inhibition and electrical inhibition. The formers are mediated by chemical transmitter. Examples of functional inhibition are presented. They explain its role in the coordination of movement and posture, in the integration of the sensation and in the behaviour.
