Another mystery explained.

from Scientific American:
The answer lies at the back of the brain in an area called the cerebellum, which is involved in monitoring movements. Our studies at University College London have shown that 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.

Thanks! My boys and I have wondered about this....

Your daughter is at our house right now, sleeping in with our daughter. :) Thanks for sparing her for these two years! She has made a difference in our MKs' lives.

Thank you, Patricia! Glad to know she's in good hands. And to think we didn't use to let her cross the street alone!
