*Synesthesia (also spelled synæsthesia or synaesthesia, plural synesthesiae or synaesthesiae) —from the Ancient Greek σύν (syn), meaning “with” and αἴσθησις (aisthēsis), meaning “sensation” —is a neurological condition in which otherwise normal people experience the blending of two or more senses. In one common form of synesthesia, known as grapheme → color synesthesia, letters or numbers are perceived as inherently colored, while in ordinal linguistic personification, numbers, days of the week and months of the year evoke personalities. In spatial-sequence, or number form synesthesia, numbers, months of the year, and/or days of the week elicit precise locations in space (for example, 1980 may be “farther away” than 1990), or may have a three-dimensional view of a year as a map (clockwise or counterclockwise). —Definition from Wikipededia.
* “If you ask synesthetes if they wish to be rid of it, they almost always say no. For them, it feels like that’s what normal experience is like. To have that taken away would make them feel like they were being deprived of one sense.”
—Simon Baron-Cohen, synesthesia researcher at the University of Cambridge.
* “Synesthesia has implications for every major aspect of cognition: perception, attention, language, memory, emotion, and consciousness. In turn, in order to understand synaesthesia, one has to consider these aspects as well as their development and neural basis.” —Noam Sagiv
* “Synesthesia is a love story between the senses” —Dr. Hugo Heyrman
