WebbInhibitory control is broadly conceptualized as the ability to suppress or countermand a thought, action, or feeling. Many investigators study inhibitory control using carefully designed tasks like the stop-signal task, or the go/no-go task, that measure an individual's ability to suppress a prepotent motor response. WebbInhibitory neurotransmitters (GABA) GABA is the main neurotransmitter involved in inhibitory postsynaptic potentials (IPSP). On binding to postsynaptic neuron receptors, GABA opens specific ion channels which are different from those opened in EPSP by excitatory neurotransmitters like Glutamate.
