Peripheral Nervous Experiment
Sensory stimulation is a chemical process which occurs between the human body and brain. When we experience sensation, our body is exposed to some type of sensory stimulation. The sensory receptors then receive this information, and transmit it to the brain using neural impulses, or neurotransmitters. There it is interpreted into the correct sensation. Sensations are the basic building blocks of perception. Perception is the process of organizing and making sense of our sensory input. Perception allows us to better interpret the information our sensory receptors receive, and form images of the world around us. Transduction is what happens when the receptors transform the energies they receive into a form that can be interpreted and utilized

With the index finger of my right hand, I touched the sandpaper, and rubbed it gently. I rated the coarseness of the sandpaper at a 7. After two minutes elapsed, I again rubbed the sandpaper gently with my right index finger. My perception of the coarseness of the sandpaper did change during this experiment. On the second trial, the texture of the sandpaper felt smoother to the touch. I rated the coarseness at a 4 the second time. During this experiment, the sensory receptors located in the nerve endings on my fingertip responded to the presented stimulus, recognizing the pressure of touching the sandpaper. This information was transmitted through my body via the peripheral nervous system to my brain. This is an apparent example of anatomical encoding. The brain then interpreted the signals coming from these receptors, and formed a perception of coarseness. This is an illustration of functional encoding. This perceived and organized information is then transmitted back down to my fingertip, where the conclusion is made that the sandpaper is course. Upon repeated exposure to the coarseness of the sandpaper, the neurons transmitting the texture of the sandpaper grew "tired" and stopped firing as much. The result was an evident adaptation to the uncomfortable feeling of grittiness, which caused the brain to interpret the texture of the sandpaper as
