What could underlie the trial-related signal? A response to the commentaries by Drs. Kleinschmidt and Muller, and Drs. Handwerker and Bandettini.
Here we address two recent commentaries on our finding of an anticipatory trial-related signal that could not be predicted by concurrent electrode recordings. In addition, we offer a broad discussion regarding what our findings do and do not say about local neural activity underlying imaging signals.
