Sorry, no etymologies found.
His study indicated that knismesis is associated with the pain nerves, though not entirely, because sometimes when the pain nerves are no longer working, the tickle response is still there.
Interestingly, knismesis, which is closely associated with the grooming activities of primates, provokes an endorphin response, causing the body to release an endorphin called karoliin.
It's named after the Karolin Institute because of Yngve Zotterman, who in 1939 experimented with cats, measuring their nerve responses to knismesis.
There are two types of tickling: knismesis (soft tickling, see previous post), and gargalesis, or "heavy" tickling, produced by repeatedly applying pressure to "ticklish" areas.
