Secrets of the Mind was originally broadcasted on October 23, 2001. The film delves into the mind-tingling efforts of neuroscientist V.S. Ramachandran to discover how the brain works. Your mind sees the classic Necker cube either as pointing upward to the right or downward to the left—but not both at the same time, no matter how hard you try. Give the cube a peek, along with an intriguing series of other visual challenges. One patient had gnawing sensations in his phantom arm until he discovered his discarded limb was being devoured by maggots. Another felt pleasant sensations in her phantom foot every time she had sexual intercourse. Hear these and other strange tales from the phantom world, as vividly described by Ramachandran. Use an electric probe to map the motor cortex, the area of the brain responsible for controlling body movement.
