ABSTRACT
Driving is a daily requirement and an indispensable activity for many people. However, still little is known about how driving is supported by the brain. We used electroencephalography to study the changes in brain activity and its functional connectivity in a simulated driving task. We focused on overtaking and studied this activity in three phases: before overtake, during overtake, and after overtake. Our results showed that mu power in motor and sensorimotor areas decreased during overtake and again increased after overtake. On the other hand, beta oscillations in frontal areas were at their highest level in the “before overtake” phase. It can be interpreted that the “before overtake” was the most attention-demanding phase. In addition, we found that the connectivity between right and left prefrontal regions and right and left occipital regions in alpha (and mu) band power was significantly stronger in the “during overtake” compared to the other two conditions.
