The brain uses sense organs to reach out to its environment by which it responds to different stimuli such as light, sound waves, and pressure. This information is then transmitted electrically to different specialized areas of the cerebral cortex where all is processed into senses of hearing, vision, taste, touch, and smell.
Sensory Neurons react to data from certain sense organs. Visual cortical neurons are highly sensitive to information from the eyes through the optic nerves. Visuals neurons have been found to be more sensitive and react more strongly towards weak light signals coming from the optic nerve.
In most people who are blind or deaf, some some neurons that are usually to do with sight(this is in blindness) are taken over by hearing. Thus making people who cant see hear better and those who cannot hear see better. The primary visual cortex(center) is located in the back of the brain in the occipital lobe. The primary hearing cortex is found in the temporal lobes or the sides of your heads near the ears.
In Synesthesia, most people are aware of only aware of one sensation in response to to one type of stimuli. For ex. Sound waves make noise but some claim to experience more than one sensation, and they can see sound as well as hear it. They can taste images as well as see them. This is when the neural pathway from a sense organ diverges and carries data from one type of stimuli to a part of the brain where it processes it as another.
