How Are the Senses Alike? And How Are They Different?
Senses all operate similarly, but each receives different information and sends it to a specialized region in the brain. Therefore, different sensations occur because each sense activates a different part of the brain. The brain interprets physical energy from the outside world as nerve signals and processes them into ways that they can be used. These signals are received by the senses: 1. vision: the brain receives light waves from photoreceptors, such as rods and cones, that are transduced into neural signals that are sent away to be interpreted by the brain.s We look with our eyes but see with our brain. 2. hearing allows us, like vision, to locate objects in space. Sound waves with a certain frequency ( pitch ) and amplitude ( loudness ) are processed by the brain in the auditory cortex. 3. smell: (olfaction) odors interact with receptors in the nose which transfer a message to the olfactory bulbs located on the underside of the brain, which involves a chain of biochemical events. 4. gustation: (taste) soluble substances to flavors, and 5. skin senses: external contact to touch, warmth, and coldness. However, there are also people with disabilities to these senses, such as blindness and deafness (see Vision and Hearing ). We also have the vestibular senses and kinesthetic senses. The vestibular senses allow us to keep track of the position of our bodies and surroundings. it also enables us to keep balanced, for instance when running. Kinesthetic senses allow us to keep track of our body parts in relation to each other. We also have the ability to feel pain. The Gate-Control Theory states that we have a neural "gate" that is capable of blocking incoming pain signals. Many people can learn to control pain by psychological techniques such as the placebo effect. All of these senses transduce stimulus energy into the neural impulses.
