synesthesia

We generally think that humans have five senses and that those senses are delegated to a specific organ in our bodies. Anyone would agree that we see with our eyes, taste with our tongues, hear with our ears, feel with our skin and smell with our noses. While this may indeed be the case, it is not the whole story. Our senses are all interconnected. They compliment one another and can even compensate for one another if a sense is weakened or lost (1). However, the interactions between the senses are not uniform from person to person. Synesthesia, the name given to any of a number of conditions involving the experience of a usually unassociated sense in conjunction with the stimulation of another sense, provides insight into the ways our senses can interact.<
