Syneshetesia

Syneshetesia is a rare neurological condition in which an individual experiences a combination of perceptions in response to a single sensory modality. This condition causes the brain to process information in the form of several senses at once. When one sense is activated, another different sense is activated at the same time. An individual with syneshetesia may hear sounds while seeing the sounds as patterns of color at the same time.
