Much to the dismay of wacky masochist everywhere, the human brain is wired against self-tickling. Because the brain controls movement, it knows what your hand is going to do before you do it. Thus it anticipates the exact force, location, and speed of the tickle and uses that information to desensitize you to your own roving hands. So why do we have a tickle response anyway? Turns out, it’s a defense reaction meant to alert our cave-dwelling ancestors to creepy crawlies that didn’t know their place, and the uncontrollable laughing fit that goes along with it is actually a panic response.

I am very ticklish on the roof of my mouth and can tickle it with my tongue just fine. The reaction is just the same as if someone else was to do it with their finger (or tongue). hard to test other areas as I am not very ticklish elsewhere.
