Sense and Vision

J Sensation is the detection and direct experience of physical energy as a result of environmental or internal events. Perception is the process by which sensory impulses are organized and interpreted. Our Sensational Senses J Sensation begins with the sense receptors, which convert the energy of a stimulus into electrical impulses that travel along nerves to the brain. Separate sensations can be accounted for by anatomical codes (as set forth by the doctrine of specific nerve energies) and functional codes in the nervous system. In a rare condition called synesthesia, sensation in one modality evokes a sensation in another modality, but these experiences are the exception, not the rule.
