Peak Alpha Is a Biomarker of Pain Sensitivity.

Link – Sensorimotor Peak Alpha Frequency Is a Reliable Biomarker of Prolonged Pain Sensitivity. Abstract Previous research has observed that the speed of alpha band oscillations (8-12 Hz range) recorded during resting electroencephalography is slowed in chronic pain patients. While this slowing may reflect pathological changes that occur during the chronification of pain, an alternative explanation […]

Alpha-tACS effect on inhibitory control

Link – Alpha-tACS effect on inhibitory control and feasibility of administration in community outpatient substance use treatment. Abstract BACKGROUND: Deficits in inhibitory control (IC) and distress tolerance (DT) are associated with substance use disorders (SUD) and post-treatment return to substance use. Transcranial alternating current stimulation (tACS) modulates the neural oscillations that are associated with the […]

tACS Inhibitory Abilities are Linked to Numerosity Discrimination.

Link – Parietal alpha-based inhibitory abilities are causally linked to numerosity discrimination. Behav Brain Res. 2020 Feb 17;:112564 Authors: Labree B, Corrie H, Karolis V, Didino D, Cappelletti M Abstract Processing numerosities relies on the innate capacity to understand and manipulate the number of items in a set, and to additional abilities such as inhibitory […]

tACS at 10 Hz modulates response bias

Link – Transcranial alternating current stimulation at 10 Hz modulates response bias in the Somatic Signal Detection Task. Int J Psychophysiol. 2019 01;135:106-112 Authors: Craddock M, Klepousniotou E, El-Deredy W, Poliakoff E, Lloyd D Abstract Ongoing, pre-stimulus oscillatory activity in the 8-13 Hz alpha range has been shown to correlate with both true and false reports of […]

Electrical stimulation of alpha oscillations stabilizes performance on visual attention tasks.

Link – Electrical stimulation of alpha oscillations stabilizes performance on visual attention tasks. J Exp Psychol Gen. 2019 Feb;148(2):203-220 Authors: Clayton MS, Yeung N, Cohen Kadosh R Abstract Neural oscillations in the alpha band (7-13 Hz) have long been associated with reductions in attention. However, recent studies have suggested a more nuanced perspective in which […]

alpha oscillations a mechanism for inhibiting obvious associations

Link – Right temporal alpha oscillations as a neural mechanism for inhibiting obvious associations. Proc Natl Acad Sci U S A. 2018 12 26;115(52):E12144-E12152 Authors: Luft CDB, Zioga I, Thompson NM, Banissy MJ, Bhattacharya J Abstract Creative cognition requires mental exploration of remotely connected concepts while suppressing dominant ones. Across four experiments using different samples […]

Low-frequency tACS rhythmically suppresses gamma-band oscillations and impairs perceptual performance.

Link – Low-frequency alternating current stimulation rhythmically suppresses gamma-band oscillations and impairs perceptual performance. Neuroimage. 2019 01 01;184:440-449 Authors: Herring JD, Esterer S, Marshall TR, Jensen O, Bergmann TO Abstract Low frequency oscillations such as alpha (8-12 Hz) are hypothesized to rhythmically gate sensory processing, reflected by 40-100 Hz gamma band activity, via the mechanism of pulsed […]

Hearing through Your Eyes: Revealed by tACS

Link – Hearing through Your Eyes: Neural Basis of Audiovisual Cross-activation, Revealed by Transcranial Alternating Current Stimulation. J Cogn Neurosci. 2019 Mar 18;:1-14 Authors: Fassnidge C, Ball D, Kazaz Z, Knudsen S, Spicer A, Tipple A, Freeman E Abstract Some people experience auditory sensations when seeing visual flashes or movements. This prevalent synaesthesia-like “visually evoked […]

Targeting alpha-band oscillations with tACS

Link – Targeting alpha-band oscillations in a cortical model with amplitude-modulated high-frequency transcranial electric stimulation. Neuroimage. 2018 06;173:3-12 Authors: Negahbani E, Kasten FH, Herrmann CS, Fröhlich F Abstract Non-invasive brain stimulation to target specific network activity patterns, e.g. transcranial alternating current stimulation (tACS), has become an essential tool to understand the causal role of neuronal […]
