During transcranial Direct Current Stimulation (tDCS), low-intensity DC current is applied across the scalp to enhance specific performance or training efficacy on a range of complex cognitive tasks; moreover tDCS has been suggested to produce minimal side-effects (undesired cognitive changes). The central premise of this proposal if that tDCS achieves task-specific modulation through a cellular mechanism where only neuronal circuits primed during tDCS (for example by training) are modulated by tDCS, while none primed mechanisms are not modulated. The specific goal of this proposal is thus to establish a cellular substrate for DCS mediated activation-specific changes.
We will be there! The workshop is expected to sell out so reserve a spot ASAP.
Talk by Dr. Marom Bikson, Dr. Felipe Fregni, and Dr. Dylan Awards,
Hands-on workshop on tDCS and HD-tDCS (!) plus demonstration of HDexplore and HDtargets,

Focal Modulation of the Primary Motor Cortex in Fibromyalgia Using 4×1-Ring High-Definition Transcranial Direct Current Stimulation (HD-tDCS): Immediate and Delayed Analgesic Effects of Cathodal and Anodal Stimulation.
Abstract: Fibromyalgia is a prevalent chronic pain syndrome characterized by altered pain and sensory processing in the central nervous system, which is often refractory to multiple therapeutic approaches. Given previous evidence supporting analgesic properties of noninvasive brain stimulation techniques in this condition, this study examined the effects of a novel, more focal method of transcranial direct current stimulation (tDCS), using the 4×1-ring configuration of high-definition (HD)-tDCS, on overall perceived pain in fibromyalgia patients. In this patient- and assessor-blind, sham-controlled, crossover trial, 18 patients were randomized to undergo single 20-minute sessions of anodal, cathodal, and sham HD-tDCS at 2.0 mA in a counterbalanced fashion. The center electrode was positioned over the left primary motor cortex. Pain scales and sensory testing were assessed before and after each intervention. A finite element method brain model was generated to predict electric field distribution. We found that both active stimulation conditions led to significant reduction in overall perceived pain as compared to sham. This effect occurred immediately after cathodal HD-tDCS and was evident for both anodal and cathodal HD-tDCS 30 minutes after stimulation. Furthermore, active anodal stimulation induced a significant bilateral increase in mechanical detection thresholds. These interventions proved well tolerated in our patient population. PERSPECTIVE: 4×1-ring HD-tDCS, a novel noninvasive brain stimulation technique capable of more focal and targeted stimulation, provides significant reduction in overall perceived pain in fibromyalgia patients as compared to sham stimulation, irrespective of current polarity. This technique may have other applications in research and clinical settings, which should be further explored.
