A study from Switzerland provides insight to what happens to a hypnotized brain.  Volunteers in the study made a hand movement in response to a cue.  Some participants were hypnotized with the suggestion that they're left hands were paralyzed, while the others were told to act as if their left hands were not paralyzed.  MRI brain scans revealed that hypnosis was linked to a wider number of changes in brain activity in areas devoted to attention.  It also changed communication between the motor-movement areas and the rest of the brain.  It's fascinating research in the journal Neuron, and it all came out of Switzerland.
