BackgroundTranscranial direct current stimulation (tDCS) is a technique that can systematically modify behaviour by inducing changes in the underlying brain function. In order to better understand the neuromodulatory effect of tDCS, the present study examined the impact of tDCS on performance in a working memory (WM) task and its underlying neural activity. In two experimental sessions, participants performed a letter two-back WM task after sham and either anodal or cathodal tDCS over the left… 
Behavioral and Electrophysiological Effects of Transcranial Direct Current Stimulation of the Parietal Cortex in a Visuo-Spatial Working Memory Task
TLDR
It is demonstrated that posterior tDCS can alter visuo-spatial WM performance by modulating the underlying neural activity, and can be considered an important step toward a better understanding of the mechanisms involved in tDCS-induced modulations of cognitive processing.
Modulation of Working Memory Using Transcranial Electrical Stimulation: A Direct Comparison Between TACS and TDCS
TLDR
TACS resulted in a greater improvement in RT-hits than TDCS, suggesting that future work optimizing the application of TACS has the potential to facilitate WM performance.
Task-Specific Facilitation of Cognition by Anodal Transcranial Direct Current Stimulation of the Prefrontal Cortex
TLDR
It is concluded that anodal stimulation over the left DLPFC can selectively improve performance on a difficult cognitive task involving arithmetic processing, verbal working memory, and attention.
Individual Baseline Performance and Electrode Montage Impact on the Effects of Anodal tDCS Over the Left Dorsolateral Prefrontal Cortex
TLDR
It is demonstrated how individual differences in cognitive performance and electrode montages influence effects of tDCS on neuropsychological performance, and the idea of an individualized and optimized stimulation setting, potentially leading to increased tDCS effects is supported.

Bifrontal transcranial direct current stimulation slows reaction time in a working memory task
TLDR
Intermittent tDCS over lateral prefrontal cortex during a working memory task impairs central nervous processing related to response selection and preparation as indexed by event-related sustained and oscillatory EEG activity such as theta.
Anodal transcranial direct current stimulation of prefrontal cortex enhances working memory
TLDR
The results indicate that left prefrontal anodal stimulation leads to an enhancement of working memory performance, which depends on the stimulation polarity and is specific to the site of stimulation.

TLDR
This is the first trial showing that tDCS can enhance a component of recognition memory, and the potential mechanisms of action and the implications of these results are discussed.

How does transcranial DC stimulation of the primary motor cortex alter regional neuronal activity in the human brain?
TLDR
TDCS is an effective means of provoking sustained and widespread changes in regional neuronal activity and the extensive spatial and temporal effects of tDCS need to be taken into account when tDCS is used to modify brain function.
Oscillatory brain activity and transcranial direct current stimulation in humans
TLDR
It is shown here that tDCS transiently and reversibly changed the organized cortical activity elicited by visual stimulation, which might be a suitable method to affect higher order cognitive processes.

TLDR
It is shown that the tDCS technique has the potential to modulate short-term verbal learning mechanism and implies that the left DLPFC is a crucial area involved in short- term verbal learning mechanisms.
