Synesthesia is a term for a perceptual phenomenon in which stimulation of one perceptual/cognitive pathway leads to automatic, involuntary activation (cross-linking) in a second perceptual/ cognitive pathway (for example “seeing sounds”). The term synesthesia is a composite lexeme which is etymologically derived from the Ancient Greek σύν (syn) meaning “together”, and αἴσθησις (aisthēsis) meaning “sensation”. There are various types of synesthesia (e.g., color-sound, sound-taste, etc.) and the scientific literature differentiates between acquired and congenital forms (so called synesthetes). Psilocybin can temporarily induce synesthesia and is therefore an excellent tool for research on this fascinating topic.
