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...

PURPOSE Weak direct currents induce lasting alterations of cortical excitability in animals and humans, which are controlled by polarity, duration of stimulation, and current strength applied. To evaluate its anticonvulsant potential, transcranial direct current stimulation (tDCS) was tested in a modified cortical ramp-stimulation model of focal epilepsy. METHODS The threshold for localized s...

This study investigated the effect of anodal tDCS on motor control and corticomotor excitability in healthy controls, with the long-term goal of investigating the use of anodal tDCS to improve motor function in covertly aware vegetative state patients. Experiment I investigated the effects of anodal tDCS on a motor reaction time task, and found no effect of tDCS on performance, whether or not p...

30 31 In this pilot study we evaluated electroencephalographic (EEG) mean frequency changes induced 32 by prefrontal transcranial direct current stimulation (tDCS) and investigated whether they 33 depended on tDCS electrode montage. Eight healthy volunteers underwent tDCS for 15 minutes 34 during EEG recording. They completed six tDCS sessions, one week apart, testing left and right 35 direct c...

background and aim: tinnitus is an auditory phantom percept in the absence of any objective physical sound source. although advances have been made in its treatment, there is very low percent of patients that report an elimination of their tinnitus. a novel approach using noninv­asive neuromodulation has emerged as an inter­esting and promising modality for tinnitus relief. our aim in this revi...

Optical and magneto-optical properties of amorphous Gd22Fe78 (GdFe) thin films prepared by direct current (DC) sputtering on thermally oxidized substrates were characterized by the combination of spectroscopic ellipsometry and magneto-optical spectroscopy in the photon energy range from 1.5 to 5.5 eV. Thin SiNx and Ru coatings were used to prevent the GdFe surface oxidation and contamination. U...
