In recent years, it has become increasingly clear that both the power and phase of oscillatory brain activity can influence the processing and perception of sensory stimuli. Transcranial alternating current stimulation (tACS) can phase-align and amplify endogenous brain oscillations and has often been used to control and thereby study oscillatory power. Causal investigation of oscillatory phase...
The past decades have witnessed a huge interest in uncovering the neural bases of intelligence (e.g., Stelmack, & Houlihan, 1995; Stelmack, Knott, & Beauchamp, 2003). This study investigated the influence of transcranial alternating current stimulation (tACS) on fluid intelligence performance and corresponding brain activation. Previous findings showed that left parietal theta tACS leads to a t...
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...
Background: Pre-op anxiety has adverse effects on the patientchr('39')s anesthesia and treatment. Currently, electrical interventions are widely used as non-invasive methods to control pre-op anxiety and may have advantages as compared with medical therapies. This study aimed to determine the effect of transcranial alternating current stimulation on anxiety and hemodynamic response of patients ...
Spatial visual attention enhances information processing within its focus. Vision at an attended location is faster, more accurate, of higher spatial resolution, and has an enhanced sensitivity for fine changes. Earlier hypotheses suggest that the neuronal mechanisms of these processes are based on the interactions among different neuronal groups by means of cortical oscillations in the gamma r...
Background Novel interventions that delay the onset or progression of cognitive decline in older adults are extremely important, especially as proportion steadily grows. Data on transcranial Alternating Current Stimulation (tACS) suggests it may have potential for improving function; however, direct implication adults, including those with impairment is far less understood. It imperative to bet...
We present device standards for low-power non-invasive electrical brain stimulation devices classified as limited output transcranial electrical stimulation (tES). Emerging applications of limited output tES to modulate brain function span techniques to stimulate brain or nerve structures, including transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tA...
Editor's Note: These short, critical reviews of recent papers in the Journal, written exclusively by graduate students or postdoctoral fellows, are intended to summarize the important findings of the paper and provide additional insight and commentary. For more information on the format and purpose of the Journal Club, please see Review of Ali et al. In recent years, it has become evident that ...
