Document Summary
Module 4. 1: sensation and perception at a glance: sensing the world around us. Sensation: the process of detecting external events by sense organs and turning those stimuli into neural signals. Perception: involves attending to, organizing, and interpreting stimuli that we sense; it includes recognizing the sounds as a human voice and understanding that certain colours, shapes, and motion together make up the image of a human being. Transduction: when specialised receptors transform the physical energy of the outside world into neural impulses. These neural impulses travel into the brain and in uence the activity of different brain structures, which ultimately gives rise to our internal representation of the world. Sensory receptors involved in transduction are different for the different senses (i. e. , cochlea). Different senses are separated in the brain (proposed in 1826 by johannes muller, is known as the doctrine of speci c nerve energies)
