Evaluation of Driver's Brain Activity Associated with Advanced Driving Skills Such as Cornering

Tokai J Exp Clin Med. 2024 Sep 20;49(3):94-100.

Abstract

Evaluating the driving ability of a vehicle is important in the development of in-vehicle systems and the training of driving skills. Driving ability has been investigated extensively in terms of recognition, judgment, and operation. However, the role of the brain in advanced driving operations within the limits of vehicle performance has not been thoroughly investigated. In this study, we perform functional magnetic resonance imaging to evaluate brain functions associated with advanced driving skills when drivers are shown a video of cornering involving a vehicle slipping sideways. Based on the results, the skilled driver group indicates broad activity in both the right and left parietal associations, right-side primary somatosensory, left-side premotor, and supplementary motor areas. Because the premotor cortex is a region involved in the execution of movement, whereas the supplementary motor cortex is a region involved in spontaneous movement, it is assumed that the skilled drivers visualized the driving operation, and that the brain functions necessary for the operation are activated. These findings indicate that drivers with high skill levels exhibit distinctive brain activities. We believe that a further understanding regarding the brains of skilled drivers will facilitate the development of in-vehicle control that incorporates high driving skills and training.
