In recent years, the influence of alpha (7-13 Hz) phase on visual processing has received a lot attention. Magneto-/encephalography (M/EEG) studies showed that indexes excitability and task performance. Studies with transcranial alternating current stimulation (tACS) aim to modulate oscillations causally impact Here, we applied right occipital tACS (O2 location) assess functional role in series experiments. We presented stimuli at different pre-determined, experimentally controlled, phases...
Rhythmic stimulation can be applied to modulate neuronal oscillations. Such 'entrainment' is optimized when frequency individually calibrated based on magneto/encephalography markers. It remains unknown how consistent such individual markers are across days/sessions, within a session, or cognitive states, hemispheres and estimation methods, especially in realistic, practical, lab setting. We here estimated alpha (IAF) repeatedly from short electroencephalography (EEG) measurements at rest...
Transcranial alternating current stimulation (tACS) can be used to study causal contributions of oscillatory brain mechanisms cognition and behavior. For instance, individual alpha frequency (IAF) tACS was reported enhance power impact visuospatial attention performance. Unfortunately, such results have been inconsistent difficult replicate. In tACS, generally involves one frequency, sometimes individually calibrated a peak value observed in an M/EEG spectrum. Yet, the 'peak' actually...
Abstract In recent years the influence of alpha (7-13 Hz) phase on visual processing has received a lot attention. Magneto-/encephalography (M/EEG) studies showed that indexes excitability and task performance. If occipital is functionally relevant, alpha-frequency transcranial alternating current stimulation (tACS) could modulate processing. Visual stimuli presented at different pre-determined, experimentally controlled, phases entraining tACS signal should then result in an oscillatory...
As a highly social species, we constantly evaluate human faces to decide whether can trust someone. Previous studies suggest that face trustworthiness be processed unconsciously, but the underlying neural pathways remain unclear. Specifically, question remains processing of relies on early visual cortex (EVC), required for conscious perception. If bypass EVC, then disrupting EVC should impair subjective (conscious) perception while leaving objective (forced-choice) judgment intact. We...
Abstract Human cognition arises from information exchange within and between functionally connected brain networks. Alterations in such signal propagation across networks are linked to numerous disorders. Brain-wide can be experimentally studied with simultaneous transcranial magnetic stimulation (TMS) functional resonance imaging (fMRI), where TMS pulses introduce a at certain network node fMRI charts its through the network. Yet, this approach ignores fact that (network) impact of pulse...

This preprint provides an overview of the novel frontal-sensory alpha-band neurofeedback paradigm and associated results that were recently published by Mishra et al. (2021). It furthermore discusses methodological factors neuronal mechanisms might contribute to their findings, highlights why how findings are relevant for both fundamental clinical applications. commentary was written with intention sparking interest neuroscientists across a wide variety research domains be especially early...
