Document Summary
Sensation the process of detecting external events by sense organs and turning those stimuli into neural signals. We take information from the world through those 5 sensations. Perception involves attending to, organizing, and interpreting stimuli that we sense. Perception includes recognizing the sounds as a human voice and understanding that certain colors, shapes, and motion together make up the image of a human being walking toward you. Transduction specialized receptors transform the physical energy of the outside world into neural impulses. These neural impulses travel into the brain and influence the activity of different brain structures, which ultimately gives rise to our internal representation of the world. The sensory receptors involved in transduction are different for the different senses. The transduction of sound takes place in a specialized structure called the cochlea, where sound energy is converted into neural impulses that travel to the hearing centers of the brain.
