You touch the skin with two points of a caliper 13 mm apart, and the subject is able to perceive both points. Which of the following are possible explanations? O A. The two points of the calipers were within two different receptive fields, and both primary sensory neurons converged onto the same secondary sensory neuron B. The two points of the caliper were in overlapping receptive fields and lateral inhibition allowed both points to be distinguished C. The two points of the calipers were within two different receptive fields, and both primary sensory neurons converged onto separate secondary sensory neurons. O Only A and B Only B and C
