Transcranial alternating current stimulation of α but not β frequency sharpens multiple visual functions

open access: yesBrain Stimulation, 2020
Background: Transcranial alternating current stimulation (tACS) can entrain and enhance cortical oscillatory activity in a frequency-dependent manner. In our previous study (Nakazono et al., 2016), 20 Hz (β) tACS significantly increased excitability of ...

Unveiling the Different Reactivity of Bent and Linear Three-Atom-Components Participating in [3 + 2] Cycloaddition Reactions

open access: yesOrganics, 2021
The reactivity of a series of pairs of bent and linear three-atom-component (B-TACs and L-TACs) participating in [3 + 2] cycloaddition (32CA) reactions towards ethylene and electrophilic dicyanoethylene (DCE) have been studied within the Molecular ...

Parietal alpha tACS shows inconsistent effects on visuospatial attention.

open access: yesPLoS ONE, 2021
Transcranial alternating current stimulation (tACS) is a popular technique that has been used for manipulating brain oscillations and inferring causality regarding the brain-behaviour relationship. Although it is a promising tool, the variability of tACS

Hearing through your eyes: neural basis of audiovisual cross-activation, revealed by transcranial alternating current stimulation [PDF]

open access: yes, 2019
Some people experience auditory sensations when seeing visual flashes or movements. This prevalent synaesthesia-like ‘visual-evoked auditory response’ (vEAR) could result either from over-exuberant cross-activation between brain areas, and/or reduced ...

Phase-specific manipulation of rhythmic brain activity by transcranial alternating current stimulation

open access: yesBrain Stimulation, 2020
Background: Oscillatory phase has been proposed as a key parameter defining the spatiotemporal structure of neural activity. To enhance our understanding of brain rhythms and improve clinical outcomes in pathological conditions, modulation of neural ...

Transcranial alternating current stimulation modulates cortical processing of somatosensory information in a frequency- and time-specific manner

open access: yesNeuroImage, 2022
Neural oscillations can be modulated by non-invasive brain stimulation techniques, including transcranial alternating current stimulation (tACS). However, direct evidence of tACS effects at the cortical level in humans is still limited.
