This chapter examines sensation, which is a catch-all term for monitoring any state and feeding it into a physiological process. When people talk of their ‘senses’ they usually mean the five senses by which they consciously monitor features of the outside world. These senses—vision, hearing, smell, taste, and touch—provide rich flows of information and most make use of specialized organs. In all five cases, the sensory system combines two functions: measurement of a stimulus and encoding it in a way that can be transmitted via a nerve into the brain. In addition, the brain may signal back to the sensing system to modulate the way that it works.
