abstract = {Stress affects the brain at a network level: the salience
network is supposedly upregulated, while at the same time
the executive control network is downregulated. While
theoretically described, the effects in the aftermath of
stress have thus far not been tested empirically. Here, we
compared for the first time resting-state functional
connectivity in a large sample of healthy volunteers before
and after a mild social stressor. Following the theoretical
prediction, we focused on connectivity of the salience
network (SN), the executive control network (ECN) and the
default mode network (DMN). The DMN exhibited increased
resting-state functional connectivity following the
cyberball task to the key nodes of the SN, namely the dorsal
anterior cingulate cortex (dACC) and the anterior insula, as
well as sensorimotor regions and higher-order visual areas.
We conclude that this increased connectivity of the DMN with
key nodes of the SN and regions responsible for preparatory
motor activity and visual motion processing indicates a
shift towards an ‘alerted default mode’ in the aftermath
of stress. This brain response may be triggered or
aggravated by (social) stress induced by the cyberball task,
enabling individuals to better reorient attention, detect
salient external stimuli, and deal with the emotional and
affective consequences of stress.},
