Before revision:  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:  As a result of prolonging session time to three trials, VC9 biomarker (previously shown to correlate with cognitive load), exhibited a significant decrease with better individual performance shown by all behavioral measurements. In correspondence with previous research, theta decreased with lower cognitive load and higher performance and the novel biomarker , VC9 is found to be an effective biological measurement for the assessment of cognitive load while performing laparoscopic tasks using the surgical simulator.
