Final answer:
The pressure receptors on both sides of the body can be estimated using a two-point discrimination test. By feeling two separate points, it indicates that each is in the receptive field of two separate sensory receptors. The size of a single receptor's receptive field can be estimated by moving the points closer until the subject feels only one point.
Step-by-step explanation:
The pressure receptors on both sides of the body can be estimated using a two-point discrimination test. In this test, two sharp points are brought into contact with the subject's skin, and if the subject feels two separate points, it indicates that each is in the receptive field of two separate sensory receptors. By moving the points closer and retesting until the subject feels only one point, the size of the receptive field of a single receptor can be estimated.
