✦ Synopsis

Abstract

Foti et al. propose that a reward‐related brain potential component recorded from scalp EEG is generated by deep brain basal ganglia structures. Previous work, cited in their original article, provides only speculative and theoretical support for this interpretation. Based on empirical and anatomical evidence, we argue that this scalp‐recorded ERP component is highly unlikely to be generated by the basal ganglia.

## Abstract We recently demonstrated that the feedback negativity may be better understood as a reward‐related positivity that is absent on nonreward trials, and source localization revealed that this reward response may reflect activity in the striatum. In a commentary on our report, Cohen et al.
