Information Processing

Information processing involves 3 fundamental steps: TRANSDUCTION, TRANSMISSION, and PERCEPTION. The CNS continuously filters sensory information, and is capable of switching priority (i.e., paying attention).  PERCEPTION is a CONSCIOUS process; SENSATION is not.  For example, nociception is the sensation; pain is the perception.
