Neurocognitive Pattern Analysis of a Visuospatial Task: Rapidly-Shifting Foci of Evoked Correlations Between Electrodes

ABSTRACT Spatial patterns of correlation between pairs of electrodes in 15 channels of human scalp‐recorded brain potentials were determined by applying Neurocognitive Pattern (NCP) Analysis to single‐trial EEG data from 9 adults performing a visuospatial task. Spatial patterns of difference in inter‐electrode correlation between “move” and “no‐move’ trials of the task increased in magnitude through four successive 175‐ms wide analysis intervals. Just before stimulus onset, correlations of the midline frontal electrode with lateral central, parietal, and temporal electrodes distinguished the tasks (p
