TL;DR: A quantitative review of the cognitive data of transcranial direct current stimulation (tDCS) in healthy adults does not support the idea that tDCS generates a reliable effect on cognition inhealthy adults.

TL;DR: A systematic review does not support the idea that tDCS has a reliable neurophysiological effect beyond MEP amplitude modulation - though important limitations of this review (and conclusion) are discussed.

TL;DR: Five topics are considered, including the extensive between- and within-group differences found within the tDCS literature and the need to properly examine stimulatory response at the individual level, and the lack of data concerning tDCS response reliability over time.

TL;DR: A multivariate pattern classification approach was used for the analysis of the human electroencephalogram to decode choice outcomes in a perceptual decision task from spatially and temporally distributed patterns of brain signals and showed that the starting point of the evidence accumulation process was shifted toward the previous choice, consistent with the hypothesis that choice priming biases the accumulation process toward a decision boundary.

TL;DR: The effects of tDCS on MEP amplitudes to be highly variable at the individual level is found and future studies should consider utilizing a more strict experimental protocol to potentially account for intra-individual response variations.
