Abstract:
The electrophysiological signature of proactive cognitive control is not well known, particularly because earlier studies did not clearly differentiate cognitive from motor preparation. We separated cognitive and motor preparation by several seconds, and provide event‐related potential (specifically, CNV), theta power, and alpha power signatures of subjects preparing for a difficult cognitive task. We further observe a CNV‐like effect in a hippocampal electrode measured intracranially during the same task in an epilepsy patient. We also observe across‐subject and across‐trial correlations of these measures with behavioral performance, strongly suggesting that they reflect proactive cognitive control processes. These results provide important constraints on theories of proactive cognitive control.
