  1. Mind Games Andrea J. Frank

  2. Where were the articles? • “Mental Ping-Pong could aid paraplegics • Found on Nature.com • August 27, 2004 • “Human Subjects Play Mind Games” • Found on Washington University News and Information • June 9, 2004

  3. Mental Ping-Pong Could aid Paraplegics • Rainer Goebel has used fMRI to train subjects to play ping-pong on a computer using only their brain signals • fMRI measures oxygen. • Increased bloodflow to area of brain = more oxygen

  4. Mental Ping-Pong Could aid Paraplegics • Players compete in real time • Players control cursor by turning thoughts “on” and “off” • Takes 3 45-minute sessions to train • In everyday life, fMRI is not portable, but EEG machines are.

  5. Human Subjects Play Mind Games • Luthardt, E. C., Schalk, G., Wolpaw, J. R., Ojemann, J. G., and Moran, D. W. (2004). A brain-computer interface using electrocoticographic signals in humans. Journal of Neural Engineering, 1, 63-71.

  6. Human Subjects Play Mind Games • Leuthardt and Moran use ECoG to train subjects to play computer games using their brain signals • ECoG is an invasive technique that measures activity right from the brains surface • ECoG has a higher resolution than EEG • Faster than EEG (takes months to train) • ECoG training takes about an hour

  7. What is this technology used for? • Both research teams are hoping to use these devices to help disabled populations • E.g., communication device, control artificial limbs, wheel chair control.

  8. How does this technology apply to class? • Operant conditioning -- Chap. 7 • Memory and cognition -- Chap. 14
