Response to Holroyd et al.: Oscillation dynamics enable (the investigation of) networks

摘要

Constructive criticism and questioning from colleagues are critical to the progression of science. We thank Holroyd, HajiHosseini and Baker for their commentary [1] on our recent Opinion article [21. However, it seems that Holroyd et al. misunderstood the purpose of our Opinion piece. Our goal was to point out that learning and behavior adaptation are achieved by more than just the anterior cingulate and a midbrain dopamine region, and to proffer novel, testable hypotheses grounded in neurophysiological processes for how large-scale cortical networks support learning from valenced feedback. The point of our article was not, as they wrote, to 'discuss the relative strengths of the event-related brain potential (ERP) and time-frequency (TF) techniques for investigating cognitive function'. Because TF- and synchronization-based approaches offer the opportunity to study interactions among large-scale networks with physiologically meaningful data interpretations, these methods are better suited than ERPs to test the hypotheses outlined in our Opinion article.
