Facts about Synesthesia
2-4% of the population is born with synesthesia
Synesthetes have increased grey and white matter in the inferior temporal lobe, a section which is crucial for visual recognition
Any combination of the senses is possible: some people can see tastes or even hear smells (wow, it sure sounds delicious in here!)
Drugs and Synesthesia
Hallucinogens such as LSD, mushrooms, or DMT all mess with your senses, and can cause temporary synesthesia.
Drugs such as LSD never leave your system, and alter your serotonin receptor sites
This means that the drug could become active again at any time for the rest of your life.
If this happens, synesthesia can become permanent.

What is Synesthesia?
Synesthesia is a condition in which one normal sense, such as sight or smell, is perceived by one or more senses at the same time. In the most common form, color-grapheme synesthesia, specific colors are seen when viewing certain letters or numbers
. Someone with color-graphe
me synesthesia would view every letter in this paragraph as having its own color.

Living with Synesthesia
Daniel Tammet used his ability to see numbers as organized colors to memorize 22,514 digits of Pi.
Art and Synesthesia
Artists such as Robin Fox have tried to recreate synesthesia in art form.
Some scientists argue that these don't technically show what a synesthete experiences, but each person's experience is so unique that it's impossible to say for sure.
