Through sensation, we form an immediate and relevant picture of the world and our place in it, informed by our past experience and preparing us for probable futures. Sensation provides immediate answers to three ongoing and essential questions: Is something there? What is it? and What’s changed? To answer these questions, all sensory systems perform two fundamental functions: detection and discrimination. Because our world and our needed responses to it change with time, sensory systems can both preferentially respond and adapt to changing stimuli in the short term, and also learn to modify our responses to stimuli as our needs and circumstances change.
