Classification of stimulus- and target-related connections. (A) SI for one subject for a typical stimulus-related (Left, occipital to posterior parietal left) and a typical target-related (Right, frontal left to posterior parietal right) connection. SI was computed based on sensor groups that are most sensitive to a given region. (B) Autocorrelations were computed for the time course of synchronization for each pair of connections. Connections showing a significant peak at 146 ms were classified as stimulus-related (Left shows an example, to cingulum), and connections showing a significant peak at 292 ms were classified as target-related (see Right for an example, frontal left to frontal right). The dashed line represents the 99% confidence limit computed from 1,000 random permutations of the SI time course. (C) The stimulus-related (Left) and target-related (Right) networks are shown with linewidth coding for the strength of synchronization at 260 ms.
