In the process of sensory coding    Recruitment of additional neurons occurs with a weak stimulus in order to make the stimulus stronger.   The larger the receptive field of a sensory receptor, the greater the expected acuity and the more accurate the two-point discrimination.    Lateral inhibition of neighboring receptors resulting in a relative reduction of action potentials in the neighboring second order neurons would be expected to increase acuity.   A receptor potential that remains suprathreshold into the absolute refractory period will result in additional action potentials.
