Enhancing and Degrading Piloting Performance and Learning using TDCS.


he objective of these experiments was to determine neural correlates underlying modulation of performance by tDCS on a difficult piloting task. TDCS passes low amplitude current through the head. The mechanisms underlying the modulatory effects on motor behavior and performance are still not understood. Preliminary results suggest that performance on a piloting task can be modulated by TDCS. Cathodal stimulation had reduced behavioral performance which was reflected in reduced performance modulated activity in Prefrontal and PMC as well as parietal areas post- relative to -pre stimulation. Differences in performance modulated activity post- relative to pre- stimulation suggest that Anodal stimulation has a beneficial enhancement in contralateral PMC.
