An increase in stimulus intensity results in an increase in the rate of nerve firing by the touch receptor's axon. This is due to a greater number of receptor potentials generated by the touch receptor, which results in a greater number of action potentials in the axon. The size of the nerve impulses and the speed of nerve conduction remain constant.
