Synesthesia is peculiar yet almost envious condition in which the person either sees sounds, taste shapes, or feels colors. A synesthete may have one or more form of the condition! Their senses mix with what they are seeing, touching, or hearing. For example: they'll see the number 5 but will correlate it with the color green; the image flashes through their minds. Little is known about what causes their conditions but scientist now assure that those bizarre sensation are real; they are not make up by the person. To the synesthetes this condition is like an additional sense, a way of living; is as normal as knowing that a circle is round. Yet not all synesthetes are alike. For example one synesthete will see the number 6 and in their minds see orange yet another synesthete will see it purple. Another could feel a shape (external) when another will see it "inside" their head (internal). Synesthetes aren't more vulnerable to mental problems then the non-synesthetes and there's also no evidence that they'll incline to the arts. Yet the artist that do have it are more open and can explain it better then those who aren't because they don't see is a something to be shamed of.
Dr. Grossenbacher made a theory stating: that synesthetes have abnormally strong feed backward activity in their cortical sensory pathways. A real conclusion is hard to pin down because no one can really go into a synesthetes' head and perceive what they see, hear, or feel! And there are few set facts about it. But research in this condition has encouraged synesthetes to come "out" into the open and give a name to their out of the ordinary sensations. Most often feel lonely because they feel abnormal and no one can actually relate. Some have found support and understanding throughout the Internet. Synesthetes see the world differently and to many "normal" people this condition it not a bad condition at all.
A neurologist Cytowic did an experiment 20 years ago on Michael Watson (a synesthetes) after Michael Watson inhaled a radioactive xenon gas that diffused into his bloodstream he sniffed difference fragrances and as always he started to fill invisible shapes pressing against his skin Using a device that tracks blood flow Cytowic noticed that the flow to Watson's cortex (outer layer of gray matter of the cerebrum and cerebellum that contains most of the higher nervous centers as those concerned with
