Transcript of Synesthesia

What is synesthesia?
crossing of the senses
develops during childhood
about 1 in 2,000 people have synesthesia
comes in many different forms
different depending on the individual
hear color
see sounds
taste shapes
different letters and numbers have different colors, tastes, sounds and even personalities
Sound-to-color
Sound triggers the visualization of colored generic shapes
for some people only a few sounds will trigger a perception
usually the perceived colors appear in generic shapes, squares, circles, triangles
Personification
will associate ordered sequences with various personalities
ordered sequences may include numbers, letters, months, and so on
personality within
an object

Lexical-gustatory
very rare
different tastes when you hear certain words or sounds
Where in the brain does synesthesia occur?
unclear which parts of the brain are involved
limbic system is primarily responsible
colored-hearing synesthetes have been shown to display activity in several areas of the visual cortex when they hear certain words
in synesthetes, neurons and synapses that are "supposed" to be contained within one sensory system cross to another sensory system
