The feeling you get when your tickeled is actually a fear or panic response so if you do it to yourself your not afraid of yourself nor are you going to try to get away from yourself because your body knows its you touchin your own body so it doesnt feel the need to warn you of possible danger
Actually tickling by others is something that you are not aware of and if also aware you don't know where the person is going to Tickle you When you are tickling yourselves you are very aware what you are doing that's the reason.. Nice Question by the way...
You can actually tickle yourself, I know of two spots, that you can get a slight tickle. It is not, exactly the same feeling as with another persons doing it though. It is above the roof of your mouth, and also where they do bloodwork. Use your fingertips very slightly and tickle back-and-forth and you'll get tickle out of it
I once went on a quest of self exploration, not for the purposes of tickling myself, but the details are somewhat inconsequential. I was able to locate a spot on the anterior portion of my left knee that, while completely un-ticklish to anyone other than myself elicited a catastrophic response that sent me into paroxysms of uproarious laughter. It might be noted for didactic purposes that perhaps this was not the best timing on my part, as I was at the time driving an 18-wheel transport. Unable to control myself, I obliterated no less than 7 other vehicles on the motorway and was forced to abandon the rig and flee the scene. That was three years ago. My wife and two children have no idea what became of me and I am still a wanted fugitive. I now run an armadillo farm under the pseudonym Armando Sanchez and am only able to take small moments of comfort amidst the ruin of a shattered life late at night when I am alone by tickling myself to the brink of delirium. The moral of the story is that one should not tempt fate nor soar to close to the heavens lest they risk ruination of all they hold dear...or really like armadillos.
here our nervous system plays a big role..wen some1 tickles u..at dat moment ur nervous system is not aware of d situation n so it doesn't send any signal 2 d brain pertaining to d situation...on d contrary wen u tickle urself.. ur nervous system is completly aware of d situation..n so its sends corresponding signals to d brain...so u don't feel ticklish..
NYAN NYAN NYAN GOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I LOVE PNIES AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHThe human brain anticipates unimportant sensations, such as your own touch, so it can focus on important input like, say, a tarantula crawling up your neck. The results might explain why it's hard to tickle yourself, scientists said today. In the study, 30 people used a finger on their right hand to touch a finger on their left hand by tapping a device place directly over the left finger and could instantly relay the tap. Bottom line: When their brains expected a tap and the tap came as expected, the brain noticed it less. "It lends support to the theory that the brain is constantly predicting what is about to happen, what sensations it's about to receive," Why do our minds work this way? The information we get from our senses is always a little out of date, because it takes time for the electrical signals to travel from the finger, ear or eye to the brain. The study is detailed in a recent issue of the journal Current Biology. Didn't expect that, did'ya?
