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 activity significantly decreased with higher participants performance both in Exp.2 and in Exp. 3. Altogether , VC9 , showed higher sensitivity to load changes. Together, these measurements might be for neuroimaging assessment of cognitive load while performing laparoscopic tasks using the surgical simulator.
