abstract = {Anticipatory brain activity makes it possible to predict the occurrence of expected
situations. However, events such as traffic accidents are statistically unpredictable
and can generate catastrophic consequences. This study investigates the brain activity
and effective connectivity associated with anticipating and processing such
unexpected, unavoidable accidents. We asked 161 participants to ride a motorcycle
simulator while recording their electroencephalographic activity. Of these, 90
participants experienced at least one accident while driving. We conducted both
within-subjects
and between-subjects
comparisons. During the pre-accident
period,
the right inferior parietal lobe (IPL), left anterior cingulate cortex (ACC), and
right insula showed higher activity in the accident condition. In the post-accident
period, the bilateral orbitofrontal cortex, right IPL, bilateral ACC, and middle and
superior frontal gyrus also showed increased activity in the accident condition.
We observed greater effective connectivity within the nodes of the limbic network
(LN) and between the nodes of the attentional networks in the pre-accident
period.
In the post-accident
period, we also observed greater effective connectivity
between networks, from the ventral attention network (VAN) to the somatomotor
network and from nodes in the visual network, VAN, and default mode network
to nodes in the frontoparietal network, LN, and attentional networks. This suggests
that activating salience-related
processes and emotional processing allows
the anticipation of accidents. Once an accident has occurred, integration and valuation
of the new information takes place, and control processes are initiated to
adapt behavior to the new demands of the environment.},
