BACKGROUND Typically, transcranial direct current stimulation (tDCS) treatments for depression have used bifrontal montages with anodal (excitatory) stimulation targeting the left dorsolateral prefrontal cortex (DLPFC). There is limited research examining the effects of alternative electrode montages. OBJECTIVE/HYPOTHESIS This pilot study aimed to examine(More)
Transcranial direct current stimulation (tDCS) is a neuromodulatory technique which involves passing a mild electric current to the brain through electrodes placed on the scalp. Several clinical studies suggest that tDCS may have clinically meaningful efficacy in the treatment of depression. The objective of this study was to simulate and compare the(More)
BACKGROUND Translation of transcranial direct current stimulation (tDCS) from research to clinical practice is hindered by a lack of consensus on optimal stimulation parameters, significant inter-individual variability in response, and in sufficient intra-individual reliability data. OBJECTIVES Inter-individual differences in response to anodal tDCS at a(More)
BACKGROUND Cutaneous discomfort is typically reported during transcranial direct current stimulation (tDCS), restricting the current intensity and duration at which tDCS can be applied. It is commonly thought that current density is associated with the intensity of perceived cutaneous perception such that larger electrodes with a lower current density(More)
OBJECTIVE The objective of this study was to examine the effect of transcranial random noise stimulation (tRNS) with and without a direct current (DC) offset on motor cortical excitability and compare results to transcranial DC stimulation (tDCS). METHODS Fifteen healthy participants were tested in a within-subjects design. Motor-evoked potentials were(More)
