Why can't you tickle yourself?

Controlling our laughter is really tough sometimes especially when someone tickles....right? But "Why is it that you can't tickle yourself?" Let's explore!
  
It's darn near impossible to tickle yourself, and the mechanics behind the non-phenomenon of self-tickling are pretty straightforward: Your subconscious mind is always one step ahead of you. 

When someone tickles you under your arm, or on the soles of your feet, you start laughing uncontrollably. You are tickled mostly because of surprise. Even if you know you're about to be tickled, you don't necessarily know where, so you react by being ticklish. When you try to tickle yourself, it usually doesn't work, because your brain already knows how you're going to do it. To put it simply, you can't tickle yourself because you can't surprise yourself! The feeling you have when you are tickled is actually similar to what you feel when bugs or spiders crawl on you. Your reaction to tickling is actually the brain's reaction to an unexpected sensation, whether it is a tickle, or the crawly feeling of an insect on your body.

Speaking in a scientific way the brain's part the cerebellum can predict sensations when your own movement causes them but not when someone else does. When you try to tickle yourself, the cerebellum predicts the sensation and this prediction is used to cancel the response of other brain areas to the tickle. 

Two brain regions are involved in processing how tickling feels. The somatosensory cortex processes touch and the anterior cingulate cortex processes pleasant information. Its found that both these regions are less active during self-tickling than they are during tickling performed by someone else, which helps to explains why it doesn't feel tickly and pleasant when you tickle yourself.
