Event-related potential activity in the basal ganglia differentiates rewards from nonrewards: temporospatial principal components analysis and source localization of the feedback negativity: commentary

Hum Brain Mapp. 2011 Dec;32(12):2270-1. doi: 10.1002/hbm.21358. Epub 2011 Aug 8.


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.
