Sensory Receptors 2 Record the localization error distance for the same four body regions used in the previous test. An adaptive advantage of our complex nervous system involves being able to sense changes in our environment. C. Adaptation of Touch Receptors We receive signals to our central nervous system via the 1 With the subject eyes closed, have a lab partner place afferent division of our peripheral nervous system. In a coin on the inside of the subject’s forearm. general, these are the signals we receive from our 5 senses : sight, hearing, touch, taste, and smell. We also 2 Determine how long (in seconds) the initial pressure have a multifaceted sense of equilibrium. The next sensation persists. exercises will look at some of these senses in more depth to determine how they work to send signals to your brain. 3 Repeat the experiment at a different forearm location, and when the sensation disappears have your partner Exercise 1: Cutaneous Receptors add two more coins of the same size. Does the Aim: Test mechanoreceptors and thermoreceptors in the skin. pressure sensation return, and if so, how long does it last with the added coins compared to one coin alone? Background Touch receptors are not evenly distributed throughout all D. Webers law parts of the body. When a constant stimulus is applied to a 1 With eyes closed, have the subject place one hand on sensory receptor, it responds best initially, and the response
