As transcranial electrical stimulation (tES) protocols advance, assumptions underlying the technique need to be retested to ensure they still hold. Whilst the safety of stimulation has been demonstrated mainly for a small number of sessions, and small sample size, adverse events (AEs) following multiple sessions remain largely untested. Similarly, whilst blinding procedures are typically assumed to be effective, the effect of multiple stimulation sessions on the efficacy of blinding procedures also remains under question.

This approach can benefit one individual, but be ineffective or even detrimental for another. Studying the efficacy of the large range of different parameters for different individuals is costly, time-consuming and requires a large sample size that makes such research impractical and hinders effective interventions.

We examined the Feedback-Related Negativity (FRN) and P3b in relation to self-reported externalizing behavior among 78 adolescents (11-18 yrs) during a monetary gambling task with concurrent high-density electroencephalogram. As expected, the P3b and the FRN demonstrated greater evoked activity to reward and punishment, respectively.
