Bits and Pieces on Hypnosis

(MRI) scans of persons reading words have shown that the act of reading a  verb that refers to a face, arm, or leg action causes increased blood flow and  activity in the motor cortex. The areas of the motor cortex that are active correspond to sites of the motor cortex that are associated with that activity.  For example, reading the word lick would increase blood flow in sites  corresponding to tongue and mouth movements.
