In this study, we aim to obtain a better and precise understanding of brain activities of inhibition mechanism in emergencies situations, which is of great benefit for devolvement of driving assistant system. Two virtual realistic driving experiments based on stop signal paradigm were performed for 15 subjects to study Electroencephalography (EEG) brain dynamics. In addition, Independent component analysis (ICA) and event-related spectral perturbation (ERSP) analysis were applied for investigating power changes in emergency driving. We found that theta (4-7Hz) and delta (1-3Hz) power increases in Frontal and Central areas reflect inhibition process. In previous inhibition studies, beta power increase in Frontal area was also related to inhibition response. However, our results suggest that this power change in Frontal area might not be a reliable EEG characteristic of inhibition in emergency driving. Furthermore, by comparing successful and unsuccessful inhibition, this study found that delta band power activities in Central area could be an EEG index for implementing prediction systems.
