Before revision:  Exp 1 results exhibited an improvement in behavioral performance with no correlations to VC9. As a result of prolonging session time to three trials, VC9 activity significantly decreased with higher participants performance both in Exp.2 and in Exp. 3. Altogether , VC9 is found to be an effective biological measurement for the assessment of cognitive load while performing laparoscopic tasks using the surgical simulator.
After revision:  Exp 1 2, the theta band activity significantly decreased with better individual performance, as exhibited by some of the behavioral measurements of the simulator. The novel VC9 activity significantly decreased with higher participants performance both in Exp.2 and in Exp. 3. Altogether , VC9 is found to be an effective biological measurement for the assessment of cognitive load while performing laparoscopic tasks using the surgical simulator.
