Brain imaging reveals that complex driving tasks, like navigating busy intersections, activate widespread brain networks. Distracted driving shifts brain activity from visual areas to the prefrontal cortex, impacting attention.

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Transportation Safety

Background:

  • Non-invasive brain activity measurements are crucial for understanding driving ability.
  • Previous research has not fully elucidated the neural mechanisms underlying driving behavior under varying cognitive loads.

Purpose of the Study:

  • To identify the specific brain regions involved in human driving behavior.
  • To visualize neural activity during driving under different demand levels, including distraction and complex maneuvers.

Main Methods:

  • Utilized a driving simulator integrated within a 3.0 Tesla functional magnetic resonance imaging (fMRI) system.
  • Participants performed driving tasks of varying complexity, including simple turns and left turns at busy intersections.
  • Assessed the impact of distraction by having participants complete an auditory task concurrently with driving, simulating hands-free device use.

Main Results:

  • A broad network of brain areas was activated, particularly during complex maneuvers like left turns at busy intersections.
  • Distracted driving led to a significant shift in brain activation from posterior visual and spatial areas to the prefrontal cortex.

Conclusions:

  • The brain reallocates resources from posterior visual attention areas to the prefrontal cortex to manage secondary cognitive tasks during distraction.
  • These findings enhance the scientific understanding of the neuro-cognitive mechanisms of driving behavior and inform future clinical research.
