abstract = {In the electroencephalogram (EEG), early anticipatory
processes are accompanied by a slow negative potential, the
initial contingent negative variation (iCNV), occurring
between 500 and 1500 ms after cue onset over prefrontal
cortical regions in tasks with cue-target intervals of about
3 s or longer. However, the temporal sequence of the
distributed cortical activity contributing to iCNV
generation remains unclear. During iCNV generation,
selectively enhanced low-beta activity has been reported.
Here we studied the temporal order of activation foci in
cortical regions assumed to underlie iCNV generation using
source reconstruction of low-beta (13–18 Hz) activity.
During the iCNV, elicited by a cued simple reaction-time
task, low-beta power peaked first (750 ms after cue onset)
in anterior frontal and limbic regions and last (140 ms
later) in posterior areas. This activity occurred 3300 ms
before target onset and provides evidence for the temporally
ordered involvement of both cognitive-control and
motor-preparation processes already at early stages during
the preparation for speeded action.},
