Transcranial 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 کاملTranscranial alternating current stimulation attenuates visual motion adaptation.
Transcranial alternating current stimulation (tACS) is used in clinical applications and basic neuroscience research. Although its behavioral effects are evident from prior reports, current understanding of the mechanisms that underlie these effects is limited. We used motion perception, a percept with relatively well known properties and underlying neural mechanisms to investigate tACS mechani...
متن کاملFlicker-Driven Responses in Visual Cortex Change during Matched-Frequency Transcranial Alternating Current Stimulation
We tested a novel combination of two neuro-stimulation techniques, transcranial alternating current stimulation (tACS) and frequency tagging, that promises powerful paradigms to study the causal role of rhythmic brain activity in perception and cognition. Participants viewed a stimulus flickering at 7 or 11 Hz that elicited periodic brain activity, termed steady-state responses (SSRs), at the s...

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...
