Document Summary

The world outside the human body is full of light, sound vibrations and objects we can touch. At the sensory level, all of this raw sensory information (noise or sight of a person) is relayed to the brain- this is where perception occurs: perception- involves attending to, organizing and interpreting stimuli that we sense. Perception includes recognizing the sounds as a human voice and understanding that certain colours, shapes and motion together make up the image of human being walking toward you. The raw senasations detected by sensory organs are turned into information that the brain can process through transduction. Transduction: when specialized receptors transform the physical energy of the outside world into neural impulses. These neural impulses travel into the brain and influences the activity of different brain structures, which ultimately gives rise to our internal representation of the world. The sensory recpetors involved in transduction are different for the different sense.
