These experiments show that the brain makes decisions prior to you being aware you made a decision. This is something to mull over a while, and is a little unsettling. Basically, this could indicate that the concept that your behavior is based on your active decision-making is in incorrect. Your brain may decide your behavior, and your active decision-making is an illusion of your brain.
The colors indicate key parts of the brain activated by stimuli in five fMRI studies. The illustration shows activity in one hemisphere of the brain; most neural responses occur in both hemispheres.
