Frontal cortex tracks surprise separately for different sensory modalities but engages a common inhibitory control mechanism

A) A reanalysis of the single-trial model fitting analysis for the winning model (separate surprise terms cf. Fig 4A) using just the one IC that was selected to reflect the stop-signal P3 in the merged dataset. The significant association between fronto-central EEG activity following unexpected cues in the CMO task and the surprise model is retained when the data is reconstructed solely using that one ICA (out of ~17.1 overall ICs that were extracted per subject on average). B) For comparison, no significant association was found when the data were reconstructed based on the ~16.1 ICs that did not reflect the stop-signal P3.
