“…Regarding the putative target of these frontal nodes, two other studies of PES recorded the STN-LFP in DBS patients (Cavanagh et al, 2014; Siegert et al, 2014). Both studies showed that STN activity was increased following errors, and related to PES on the next trial (the studies differ slightly in the time window at which they identify STN activity that predicts PES; Siegert et al showed that the phase-locked LFP at around 300ms following the erroneous response correlated with PES, while Cavanagh et al showed that the event-related spectral perturbations in the theta frequency immediately before the next response related to PES).…”

“…The studies which compared drug-naive PD patients with chronically medicated PD patients did not report Ne/ERN amplitude differences between these groups, neither when the latter patients were on medication (Stemmer et al, 2007) nor when they were off medication (Beste et al, 2009b) during testing. In a more recent study, Siegert et al (2014) found differential effects of dopaminergic therapy on task performance in a flanker task depending on the patients' age and disease onset, supporting a dopamine overdose effect in younger patients with early onset of PD; these behavioral changes corresponded to the modulation of Ne/ERN amplitudes.…”

“…Such studies may help to reveal the role of the stimulated basal ganglia nuclei for specific cognitive processes and their ERP correlates. In addition, DBS allows for electrophysiological recordings directly from the stimulated site (i.e., the recording of local field potentials; e.g., Siegert et al, 2014) and thus provides the possibility to examine electrophysiological correlates of cognitive processes at the level of neuronal populations (Münte et al, 2008). …”

“…Our results suggest that rIFG implements memoryreliant inhibitory processes after negative feedback in particular as indicated by our fMRI results and thus plays a role in generating the post-error slowing. Unlike tasks that require immediate error correction, such as the classical Eriksen Flanker task (Siegert et al, 2014) or a Simon task (e.g., Danielmeier, Eichele, Forstmann, Tittgemeyer, & Ullsperger, 2011;King, Korb, von Cramon, & Ullsperger, 2010), feedback has little conceptual meaning for the immediate subsequent pair-unspecific trial in the current reinforcement learning task. Previously, no speed adjustments have been found on the direct next trial (Cavanagh et al, 2010;Frank et al, 2007), and we even find post-error speeding on the direct next trial.…”
