Abstract

The stop-signal paradigm has been commonly applied as a measure of inhibitory control due to its exclusive ability to capture theoretically important parameters related to the response inhibition. To observe the inhibitory function in realistic environmental settings, we designed a battlefield scenario (BFS), which is inspired by real condition like open fire between soldier and terrorist for saving civilian because terrorism is serious problem worldwide. The stop-signal task has been widely adopted as a way to parametrically quantify the response inhibition process. This study compared the response inhibition in two different scenarios: One used traditional simple visual symbols as go and stop signals i.e. symbol scenario (SBS), and the other translated the typical design into a battlefield scenario. The outcomes confirmed that both scenarios induced increased activity in the right inferior frontal gyrus (IFG) and pre supplementary motor area (preSMA), which have been associated to response inhibition. Particularly, in right temporoparietal junction (rTPJ) we found both higher BOLD activation and EEG power modulation in the battlefield scenario than in the traditional scenario after the stop stimulus onset.
