Results: A widely distributed brain network was identified, especially when making left turns at busy intersections compared to more simple driving tasks. To assess the effects of driving while distracted, participants were asked to perform an auditory task while driving analogous to speaking on a hands-free device and driving. To identify the brain areas involved while performing different real-world driving maneuvers, participants completed tasks ranging from simple (right turns) to more complex (left turns at busy intersections).

Materials and Methods: To capture brain activity during driving, we placed a driving simulator with a fully functional steering wheel and pedals in a 3.0 Tesla functional magnetic resonance imaging (fMRI) system. The current study aimed to identify the neural underpinnings of human driving behavior by visualizing the areas of the brain involved in driving under different levels of demand, such as driving while distracted or making left turns at busy intersections.
Introduction: Non-invasive measurements of brain activity have an important role to play in understanding driving ability. 9Department of Medical Biophysics, Faculty of Medicine, University of Toronto, Toronto, ON, Canada.8Department of Medicine and Institute of Health Policy, Management and Evaluation, University of Toronto, Toronto, ON, Canada.7Toronto Rehabilitation Research Institute, University Health Network, Toronto, ON, Canada.6Rotman Research Institute, Baycrest, Toronto, ON, Canada.5Department of Medicine, Baycrest Geriatric Health Care Centre, Toronto, ON, Canada.4Department of Physical Sciences, Sunnybrook Research Institute, Toronto, ON, Canada.3Institute of Biomaterials and Biomedical Engineering, University of Toronto, Toronto, ON, Canada.2Department of Surgery, Faculty of Medicine, Division of Neurosurgery, University of Toronto, Toronto, ON, Canada.1Keenan Research Centre of the Li Ka Shing Knowledge Institute, St.Schweizer 1,2,3*, Karen Kan 3, Yuwen Hung 1, Fred Tam 4, Gary Naglie 5,6,7,8 and Simon J.
