HOW DOES THE ANTICIPATION OF A TICKLE AFFECT YOU?

Hypothesis
I think when someone comes toward you and is about to tickle you, your brain thinks you are in trouble and so you tense up and back away.

Research
Martin Ingvar and his team at the Karolinska Institute of Stockholm, Sweden wanted to know why this happened. They used a brain scan called functional magnetic resonance imaging (fMRI). They compared brain images of what happens during a real tickle and an anticipated tickle.

Research
They found that an anticipated tickle activated the same areas as a real tickle. The main areas that "lit up" were the primary somatosensory cortex and secondary somatosensory cortex stating that the brain appears to be able to predict what the sensation is going to be.

Research
Visualizing possible outcomes might speed up response time to potentially dangerous stimuli such as rapidly approaching objects and may be important for avoiding or catching objects.

Conclusion
I was kind of right. The brain is able to know what is going to happen and sort of acts like something dangerous is coming at you.
