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. As surgical simulations allow to gain important skills and experience needed to perform procedures without any patient risk, it is crucial to fully evaluate and optimize the effect of these simulations on medical staff.
