Document Summary
Sensation refers to how our sense organs respond and to detect external stimulus energy, and how those responses are transmitted to the brain. Perception refers to the brain"s further processing of these detected signals that ultimately results in an internal representation of stimuli and a conscious experience of a world. Essentially, sensation detects and perception processes, and interprets. The way our sensory organs translate a stimulus"s physical properties into neural impulses is called sensory coding. Different features of the physical environment are coded by different pattern of neural impulses or transduction. Transduction is the specific process by which sensory receptors produce neural impulses when they receive stimulation. It is after transduction that the processed information get sent to the brain. Quantitative factors of stimulants are indexed by the neural firing frequency. Qualitative coding has different sensory receptors responding to different qualities of a stimulus.
