 There was also decreased activation in occipital-visual regions of the brain.When a left turn plus traffic, which already yielded the most activation of the undistracted driving tasks, had audio tasks added to the tasking, auditory, motor, somatosensory, visual, parietal, and cerebellar regions were activated.There was also significant additional activation bilaterally in the anterior brain areas, mainly in the dorsolateral prefrontal cortex and frontal polar region.
