abstract = {The suppression of distracting information in order to
focus on an actual cognitive goal is a key feature of
executive functions. The use of brain imaging methods to
investigate the underlying neurobiological brain activations
that occur during conflict processing have demonstrated a
strong involvement of the fronto-parietal attention network
(FPAN). Surprisingly, the directional interconnections,
their time courses and activations at different frequency
bands remain to be elucidated, and thus, this constitutes
the focus of this study. The shared information flow between
brain areas of the FPAN is provided for frequency bands
ranging from the theta to the lower gamma band (4–40 Hz).
We employed an adaptation of the Simon task utilizing
Magnetoencephalography (MEG). Granger causality was applied
to investigate interconnections between the active brain
regions, as well as their directionality. Following stimulus
onset, the middle frontal precentral cortex and superior
parietal cortex were significantly activated during conflict
processing in a time window of between 300 to 600ms.
Important differences in causality were found across
frequency bands between processing of conflicting stimuli in
the left as compared to the right visual hemifield. The
exchange of information from and to the FPAN was most
prominent in the beta band. Moreover, the anterior cingulate
cortex and the anterior insula represented key areas for
conflict monitoring, either by receiving input from other
areas of the FPAN or by generating output themselves. This
indicates that the salience network is at least partly
involved in processing conflict information. The present
study provides detailed insights into the underlying neural
mechanisms of the FPAN, especially regarding its temporal
characteristics and directional interconnections.},
