  2. Summer 2001

  4. Summer Program • Picture

  5. The Knot Tying Experiment • Tests how brain engages in motor learning • Subjects learn two sailor’s knots • Brain oxygenation and performance data gathered Clove hitch Bowline

  6. Hypotheses • The prefrontal cortex is involved in learning motor function • An imagery period will enhance the performance of subjects • Repetition learning in the subjects will subsequently decrease brain activation.

  7. Methods • 18 subjects randomly split into two groups • Exp group asked to imagine tying knot before trial • Control group had rest period before trial • Each subject tested 4 times with at least one day between each test • Performance was compared Control Experimental

  8. Oxygenation Prefrontal cortex Pre-frontal cortex activation was associated with imagining and actual knot-tying

  9. Best Performer Baseline Video Imagery Trial

  10. Worst performer Baseline Video Imagery Trial

  11. Performance Imagery period did not improve performance in our subjects

  12. Repetition learning Learning did occur as subjects gained experience in tying the knots, and the overall activation decreased

  13. Since Summer Program

  14. The future Thank you! Prefrontal Cortex
