The time-dependent effect of transcranial direct current stimulation (tDCS) on working memory was investigated by applying anodal stimulation over the left prefrontal cortex. This single-blind, sham-controlled crossover study recruited 15 healthy participants. A three-back verbal working-memory task was performed before, during, and 30 min after 1 mA anodal or sham tDCS. Anodal tDCS, compared w...

Kar K, Wright J. Probing the mechanisms underlying the mitigation of cognitive aging with anodal transcranial direct current stimulation. J Neurophysiol 111: 1397–1399, 2014. First published December 11, 2013; doi:10.1152/jn.00736.2013.—Meinzer et al. (J Neurosci 33: 12470–12478, 2013) have recently reported that anodal transcranial direct current stimulation (atDCS) mitigates age-related cogni...

Computational neurostimulation aims to develop mathematical constructs that link the application of neuromodulation with changes in behavior and cognition. This process is critical but daunting for technical challenges and scientific unknowns. The overarching goal of this review is to address how this complex task can be made tractable. We describe a framework of sequential modeling steps to ac...

Among currently available technologies, transcranial direct current stimulation (tDCS) is one of the most promising neuroenhancements because it is relatively effective, safe, and affordable. Recently, lay people have begun to build-or purchase-the tDCS device to use it at home for treatment or as a cognitive enhancer. The tDCS device is currently not covered by the existing regulatory framewor...

Background: Growing attention is paid to transcranial direct current stimulation (tDCS) as a novel neuromodulation method in the treatment of psychiatric illnesses. In spite of its simple procedure, electrophysiological influence of tDCS is complex and not fully understood. Therefore, its procedure and clinical application is yet to be established. To address this issue, we reviewed and summari...

Neural correlates of unfairness perception depend on who is the target of the unfair treatment. These previous findings suggest that the activation of medial prefrontal cortex (MPFC) is related to unfairness perception only when the subject of the measurement is also the person affected by the unfair treatment. We aim at demonstrating the specificity of MPFC involvement using transcranial direc...

We have previously found that transcranial direct current stimulation (tDCS) over right inferior frontal cortex (RIFC) enhances performance during learning of a difficult visual target detection task (Clark et al., 2012). In order to examine the cognitive mechanisms of tDCS that lead to enhanced performance, here we analyzed its differential effects on responses to stimuli that varied by repeti...

In the present study, we monitored hemodynamic responses in rat brains during transcranial direct current stimulation (tDCS) using functional near-infrared spectroscopy (fNIRS). Seven rats received transcranial anodal stimulation with 200 μA direct current (DC) on their right barrel cortex for 10 min. The concentration changes of oxygenated hemoglobin (oxy-Hb) were continuously monitored during...
