While polarity-specific after-effects of monopolar transcranial direct current stimulation (tDCS) on corticospinal excitability are well-documented, modulation of vital parameters due to current spread through the brainstem is still a matter of debate, raising potential concerns about its use through the general public, as well as for neurorehabilitation purposes. We monitored online and after-...

Tinnitus is usually defined as an intrinsic sound percept that cannot be attributed to an external sound source that tinnitus can be suppressed by neuromodulation techniques such as transcranial direct current stimulation (tDCS), transcranial magnetic stimulation (TMS), and transcranial electrical nerve stimulation (TENS). It is thought that TMS and tDCS modulate tinnitus directly by targeting ...

A transcranial channel is an interface between the skull and brain; it consists of a biocompatible and highly conductive material that helps convey the current induced by transcranial direct current stimulation (tDCS) to the target area. However, it has been proposed only conceptually, and there has been no concrete study of its efficacy. In this work, we conducted a computational investigation...

Transcranial direct current stimulation (tDCS) is a low-intensity, noninvasive form of brain stimulation delivered by a small battery-powered portable machine. Conventionally, 2 disposable electrodes are positioned on the head, and a small current is passed between these electrodes to stimulate the brain “transcranially.” A typical session uses a low-intensity current of 1 to 2 mA (ECT by compa...

Transcranial oscillatory current stimulation has recently emerged as a noninvasive technique that can interact with ongoing endogenous rhythms of the human brain. Yet, there is still little knowledge on how time-varied exogenous currents acutely modulate cortical excitability. In ten healthy individuals we used on-line single-pulse transcranial magnetic stimulation (TMS) to search for systemati...

J Neurophysiol 97: 3109 –3117, 2007. First published January 24, 2007; doi:10.1152/jn.01312.2006. Transcranial DC stimulation (tDCS) induces stimulation polarity-dependent neuroplastic excitability shifts in the human brai...

Purpose: Neuroscience studies suggest that Chronic Low Back Pain (CLBP) is associated with central sensitization, and maladaptive reorganization of the brain; this introduced a new target for LBP treatment. Studies revealed that cortical and peripheral electrical stimulation can be beneficial in regulating brain neuronal activity. However, there is a scarcity of evidence to support the effects ...
