10 Hz tACS over somatosensory cortex does not modulate supra-threshold tactile temporal discrimination in humans

MA Wittenberg, M Morr, A Schnitzler… - Frontiers in …, 2019 - frontiersin.org
Perception of physical identical stimuli can differ over time depending on the brain state.
One marker of this brain state can be neuronal oscillations in the alpha band (8–12 Hz). A …

Investigating the effects of transcranial alternating current stimulation on primary somatosensory cortex

N Manzo, A Guerra, M Giangrosso, D Belvisi… - Scientific Reports, 2020 - nature.com
Near-threshold tactile stimuli perception and somatosensory temporal discrimination

Beyond the peak–Tactile temporal discrimination does not correlate with individual peak frequencies in somatosensory cortex

TJ Baumgarten, A Schnitzler, J Lange - Frontiers in Psychology, 2017 - frontiersin.org
The human sensory systems constantly receive input from different stimuli. Whether these
stimuli are integrated into a coherent percept or segregated and perceived as separate …

α‐tACS over the somatosensory cortex enhances tactile spatial discrimination in healthy subjects with low alpha activity

K Saito, N Otsuru, H Yokota, Y Inukai… - Brain and …, 2021 - Wiley Online Library
Introduction Spontaneous oscillations in the somatosensory cortex, especially of the alpha

A prospective study of the impact of transcranial alternating current stimulation on EEG correlates of somatosensory perception

DD Sliva, CJ Black, P Bowary, U Agrawal… - Frontiers in …, 2018 - frontiersin.org
The (8–12 Hz) neocortical alpha rhythm is associated with shifts in attention across sensory
systems, and is thought to represent a sensory gating mechanism for the inhibitory control of …

Region-specific effects of 10-Hz transcranial alternate current stimulation over the left posterior parietal cortex and primary somatosensory area on tactile two-point …

H Yokota, N Otsuru, K Saito, S Kojima… - Frontiers in …, 2021 - frontiersin.org
Changes in α-band cortical oscillatory activity (8–13 Hz) affect perception; however, how
these changes in the left posterior parietal cortex (PPC) and primary somatosensory cortex …

Frequency specific modulation of human somatosensory cortex

M Feurra, W Paulus, V Walsh, R Kanai - Frontiers in psychology, 2011 - frontiersin.org
Oscillatory neuronal activities are commonly observed in response to sensory stimulation.
However, their functional roles are still the subject of debate. One-way to probe the roles of …

The phase of prestimulus alpha oscillations affects tactile perception

L Ai, T Ro - Journal of neurophysiology, 2014 - journals.physiology.org
Previous studies have shown that neural oscillations in the 8-to 12-Hz range influence
sensory perception. In the current study, we examined whether both the power and phase of …

10 Hz transcranial alternating current stimulation over posterior parietal cortex facilitates tactile temporal order judgment

N Otsuru, K Kamijo, T Otsuki, S Kojima… - Behavioural brain …, 2019 - Elsevier
The temporal order judgment (TOJ) task has been widely used to investigate spatial
