Synesthesia (also spelled synæsthesia or synaesthesia from the Ancient Greek σύν syn, "together", and αἴσθησις aisthēsis, "sensation") is a neurological phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. People who report such experiences are known as synesthetes.
Synaesthetes can be broadly divided into two groups. "Projector" synaesthetes experience these cross-activated perceptions in the external world, whereas "associators", experience them only in the mind's eye. And there are two main hypotheses to explain the neural basis of this increased sensory cross-talk. According to one, there is increased connectivity between normally distinct sensory pathways, because of greater neuronal outgrowth during brain development, or because exuberant connections were not properly "pruned". According to the other, the sensory cross-talk occurs because of a lack of proper inhibition.
That synaesthesia can be induced by drugs such as LSD, and that synaesthetic experiences can wax and wane with, for example, changes in mood, suggests a role for inhibitory processes mediated by the neurotransmitter GABA.
