BOLD Signal Change during Driving with Addition Task using fMRI

Abstract

This paper uses a driving wheel and pedal (working as an accelerator, brake) equipped with an MRcompatible driving simulator at a speed of 80 km/h when driving and when driving while performing secondary tasks in order to observe differences in neuronal activation (BOLD signal change). The experiments consisted of three blocks, each block consisting of both a Control phase (1 min.) and a Driving phase (2 min.). During the Control phase, the drivers were instructed to look at the stop screen and not to perform driving tasks. During the Driving phase, the drivers either drove or drove while performing addition tasks at 80 km/h. The intensity of activated voxels increased in the addition task condition compared to the driving condition in insula.
