Inhibitory control is the inhibition of behavior through involuntary and voluntary neuropsychological processes. At a voluntary level, this capacity is considered an executive function and connotes the volitional capacity to withhold behavior, particularly when invoking environmental contingencies are evident. Moreover, Inhibitory control is an ability to display acceptable conduct by resisting the temptation to commit a forbidden act.
Inhibitory postsynaptic potential (IPSP) is the presence of an ionic current flow that hyperpolarizes the postsynaptic neuron. As a result, a greater depolarization than normal is required for excitation and there is only a small probability that there will be an action potential; temporary hyperpolarization of a membrane
Inhibitory transmitter refers to neurotransmitters that cause the inside of a neuron to become negatively charged. Inhibitory transmitters decrease the probability that an action potential will be generated and are also associated with decreases in the rate of nerve firing.
Inhibitory-center-excitatorysurround receptive field refers to a center-surround receptive field in which stimulation of the center causes an inhibitory response and stimulation of the surround causes an excitatory response.
