Students need to look at what activity needs to be stopped. For instance, the acetylcholine acting as an inhibitory transmitter slows the heart beat rate. There would be no control system for integrating various sensory inputs. Parkinson's disease is a good example of the results when an inhibitory transmitter (dopamine) is not present or in low concentration. Thoughts would be confused. It would be similar to having only an accelerator pedal in the car and no brake. The car could speed up easily, but would slow down slowly. There would be only partial control of the car. The same would be true in the nervous system, if only an accelerator (excitatory neurotransmitter) were available.
