Montage Matters: The Influence of Transcranial Alternating Current Stimulation on Human Physiological Tremor
BACKGROUND Classically, studies adopting non-invasive transcranial electrical stimulation have placed greater importance on the position of the primary "stimulating" electrode than the secondary "reference" electrode. However, recent current density modeling suggests that ascribing a neutral role to the reference electrode may prove an inappropriate oversimplification. HYPOTHESIS We set out t...
متن کاملTranscranial alternating current stimulation (tACS)
Transcranial alternating current stimulation (tACS) seems likely to open a new era of the field of noninvasive electrical stimulation of the human brain by directly interfering with cortical rhythms. It is expected to synchronize (by one single resonance frequency) or desynchronize (e.g., by the application of several frequencies) cortical oscillations. If applied long enough it may cause neuro...
متن کاملTremor Suppression by Rhythmic Transcranial Current Stimulation
Tremor can dominate Parkinson's disease and yet responds less well to dopaminergic medications than do other cardinal symptoms of this condition. Deep brain stimulation can provide striking tremor relief, but the introduction of stimulating electrodes deep in the substance of the brain carries significant risks, including those of hemorrhage. Here, we pioneer an alternative approach in which we...

to the gamma band (Varela et al., 2001). This resonance-like interplay between externally applied and internally generated regional oscillatory activity may prove a powerful approach to manipulate brain activity. So far, investigations of tACS effects on cognitive performance have been limited to visual and somatosensory perception (Feurra et al., 2011b), and motor control (Pogosyan et al., 200...
متن کاملTranscranial Alternating Current Stimulation Attenuates Neuronal Adaptation.
We previously showed that brief application of 2 mA (peak-to-peak) transcranial currents alternating at 10 Hz significantly reduces motion adaptation in humans. This is but one of many behavioral studies showing that weak currents applied to the scalp modulate neural processing. Transcranial stimulation has been shown to improve perception, learning, and a range of clinical symptoms. Few studie...
