[HTML][HTML] Decomposing alpha and 1/f brain activities reveals their differential associations with cognitive processing speed
Research in cognitive neuroscience has extensively demonstrated that the temporal
dynamics of brain activity are associated with cognitive functioning. The temporal dynamics …

[HTML][HTML] The role of alpha oscillations for illusory perception
Alpha oscillations are a prominent electrophysiological signal measured across a wide
range of species and cortical and subcortical sites. Alpha oscillations have been viewed for …

Spontaneous neural oscillations bias perception by modulating baseline excitability
The brain exhibits organized fluctuations of neural activity, even in the absence of tasks or
sensory input. A prominent type of such spontaneous activity is the alpha rhythm, which …

Subjective pain perception mediated by alpha rhythms
Suppression of spontaneous alpha oscillatory activities, interpreted as cortical excitability,
was observed in response to both transient and tonic painful stimuli. The changes of alpha …

Multiple mechanisms link prestimulus neural oscillations to sensory responses
Spontaneous fluctuations of neural activity may explain why sensory responses vary across
repeated presentations of the same physical stimulus. To test this hypothesis, we recorded …

Reduced occipital alpha power indexes enhanced excitability rather than improved visual perception
Several studies have demonstrated that prestimulus occipital alpha-band activity
substantially influences subjective perception and discrimination of near-threshold or …

Dynamic relationships between spontaneous and evoked electrophysiological activity
Spontaneous neural activity fluctuations have been shown to influence trial-by-trial variation
in perceptual, cognitive, and behavioral outcomes. However, the complex …

Beta oscillations define discrete perceptual cycles in the somatosensory domain
TJ Baumgarten, A Schnitzler… - Proceedings of the …, 2015 - National Acad Sciences
Whether seeing a movie, listening to a song, or feeling a breeze on the skin, we coherently
experience these stimuli as continuous, seamless percepts. However, there are rare …

Alpha and gamma oscillation amplitudes synergistically predict the perception of forthcoming nociceptive stimuli
Ongoing fluctuations of intrinsic cortical networks determine the dynamic state of the brain,
and influence the perception of forthcoming sensory inputs. The functional state of these …
