Dermo-optical perception: the non-synesthetic "palpability of colors". A comment on Larner (2006)

By P. Brugger and P. H. Weiss


We comment on Larner's (2006) recent description of the seventeenth-century case of a blind man who could differentiate the color of objects by touch. This ability is generally known as "dermo-optical perception" and is due to the cutaneous temperature sense rather than to synesthetic processing. Although devoid of references to the phenomenon of dermo-optical perception, Larner's communication is highly valuable because it raises several issues relevant to present-day neurosciences. These comprise functional reorganization after sensory loss, handedness effects, and differences between single fingers in the sensitivity to thermal changes
