What is the role of the brain in perception?
The role of the brain in perception is to process signals from different sensory organs and make sense to them. The senses are sometimes categorized as special senses or general senses. Special senses include visual and auditory perception. Other special senses are the feeling of smell, taste and touch; The perception of touch, pressure and temperature can be categorized as general senses.
SIGHT is an important sense. Visual perception occurs when light waves enter the eye and stimulate visual receptors. These nerve impulses travel along the optical nerves; The signals are sent to the visual cortex of the occipital lobe, which is used in the perception of visual sensory data.
Another key special purpose is hearing or auditory perception, which is triggered by sound waves. Sound waves pass through sensory receptors in the ear and through the auditory nerve system. The waves are interpreted in temporary cerebral lobby, in parts of the brain known as a jack cortice.
Every nasal cavity in the nose molfactory organs that have receptors that are stimulated by odorant molecules. The odors seem to disappear, because the strange fragrance adapts quickly when the same Odorant molecule is exposed every time. The fragrances are interpreted in the olfactory bark of temporary brain lobes.
A special taste is closely related to the smell. Taste buds that are sensory organs on the tongue can detect a wide range of flavors from sweet to salt. Bitter, acidic and spicy flavors can be detected by taste buds. Chemicals in food and drinks stimulate taste receptors, while foods considered hot, such as spicy peppers, can also stimulate pain and thermal receptors. Gustatory bark of parietal lobes of the brain is used by the brain in the perception of taste.
Some senses are category -dated like general senses, including touch and pressure that are stimulated when the tissue has somehow moved. HeatIt is detected by heat and cold sensors. The body is widely distributed by free nerve endings to reduce pain while the cerebral cortex interprets the source and intensity of pain and how to respond to it.
Extrasensory perception (ESP) is a way of knowing that it is not explained through known senses. ESP examples may include reading people's mind or precisely predict the future. Although many people believe that ESP exists, it was difficult to prove the use of scientific methods and the brain perception of the ESP stimulus were not identified.
