Spatiotemporal analysis of feedback processing during a card sorting task using spatially filtered MEG.
Full Abstract
A card sorting paradigm was used to observe the neural correlates of feedback processing in adult participants. Visually presented feedback was used to indicate response accuracy and the requirement to shift response set in a 2-category card sorting task. Magnetoencephalography (MEG) responses to feedback cues were analysed using a beamformer-based spatial filtering algorithm (event-related Synthetic Aperture Magnetometry, erSAM). Analysis of source power revealed activity in rostral anterior cingulate cortex (ACC) only to negative feedback processing, which peaked at 260 ms after stimulus onset. The results are in agreement with both evidence from fMRI on spatial characteristics of negative feedback processing, and evidence from event-related potentials (ERPs) on the temporal profile of this ACC response. The superior temporal gyrus was activated only with positive feedback, reflecting integration of actions with successful outcomes. The present MEG erSAM findings are the first to provide both accurate spatial localization as well as temporal specificity for the neural correlates of feedback processing.
