Document Summary
Synesthesia means mixing of the senses" they experience sounds as colours or tastes as touch sensations that have different shapes. Women are more likely to be synaesthetes than men. Maurer suggested we are all born synesthetic neural pathways of infants are fairly indifferentiated and lead to cross modal perceptions. Transduction when a stimuli activated specialised sensory receptors translate this information into the language of nerve impulses understood by nervous system. This matching of a new stimulus with our infernal storehouse of knowledge allows us to recognize the stimulus and give it to meaning. Specific parts of the brain are specialized for different sensory functions. In people with synthesia, there is some sort of cross-wiring so activity in one part of the brain evokes responses in another art of the brain dedicated to another sensory modality. Puzzle: binding problem how do we bind all our perceptions into one complete whole while keeping its sensory elements separate.
