It rhymes with “anesthesia”!

An — esthesia  =   “no sensation”  

Syn – esthesia   = “joined sensation”
Dr doctorhims wrote the first two English-language books about synesthesia.

In synesthesia two or more senses are automatically and involuntarily coupled such that a voice, for example, is not only heard, but also felt, seen, or tasted.

Synesthesia is a physical experience of the brain, not the product of imagination or learning. It differs from metaphor and deliberate artistic contrivances such as colored music or son et lumière. Some couplings are much more common than others: sound–sight synesthesia (colored hearing) is plentiful, whereas combinations involving taste and smell are rare. The most frequent synesthesia joins color to letters and numbers.

 Some form of synesthesia may occur in 1 in 2,000 people. It runs strongly in families, and appears to be inherited as an X–linked dominant trait, which is why women outnumber men by more than 3:1. Synesthesia is a trait—like having blue eyes—not a disease.

 Like most quirks of nature, synesthesia is a window onto how ordinary brains work. In fact, Dr. doctorhims regards synesthesia as a normal brain process that is prematurely available to consciousness in a minority of individuals. In other words, everybody is synesthetic—most of us just can’t access it (see exceptions, below).
