Abstract

Sensory experience depends upon neural processing that has both passive and active components (Hagbarth 1960; Gibson 1966). The passive components involve the interaction between a stimulus and sensory receptor organs, the transduction of sensory information into patterns of nerve impulses in afferent nerve fibers, and the transmission of coded sensory information along central neural pathways to interpretive centers in the brain. The active components include the modulation of transmission in sensory pathways by centrifugal control systems originating within the brain and spinal cord, as well as the exploration or avoidance of environmental Stimuli by motor-sensory behavior.
