Sensory Systems

The sensory systems pick up changes in our environment, translate them into electrical signals, and conduct the information through the nervous system where it is processed. The body has a range of different receptor types, each one specific to a given type of stimulus, and the different sensory organs and receptors send information to specific input areas of the central nervous system. Sensory coding in the central nervous system is achieved by the type of stimulus (modality), its location, intensity, and duration.
