Oscillations are ubiquitous in electrical recordings of brain activity. While the amplitude ongoing oscillatory activity is known to correlate with various aspects perception, influence phase on perception remains unknown. In particular, since varies a much faster timescale than more sluggish fluctuations, effects could reveal fine-grained neural mechanisms underlying perception. We presented brief flashes light at individual luminance threshold while EEG was recorded. Although stimulus each...
An important effect of sustained attention is the facilitation perception. Although term “sustained” suggests that this beneficial endures continuously as long something attended, we present electrophysiological evidence perception at attended locations actually modulated periodically. Subjects detected brief light flashes were presented peripherally either or unattended. We analyzed correlation between detection performance for and unattended stimuli phase ongoing EEG oscillations, which...
Our current environment is characterized by the omnipresence of food cues. The sight and smell real foods, but also graphically depictions appetizing can guide our eating behavior, for example, eliciting craving influencing choice. relevance visual cues on human information processing has been demonstrated a growing body studies employing images across disciplines psychology, medicine, neuroscience. However, currently used image sets vary considerably laboratories characteristics (contrast,...
The brain exhibits organized fluctuations of neural activity, even in the absence tasks or sensory input. A prominent type such spontaneous activity is alpha rhythm, which influences perception and interacts with other ongoing activity. It currently hypothesized that states decreased prestimulus α oscillations indicate enhanced excitability, resulting improved perceptual acuity. Nevertheless, it remains debated how changes excitability manifest at behavioral level tasks. We addressed this...
Our current environment is characterized by the omnipresence of food cues. The taste and smell real foods-but also graphical depictions appetizing foods-can guide our eating behavior, for example, eliciting craving anticipatory cephalic phase responses. To facilitate research into this so-called cue reactivity, several groups have compiled standardized image sets. Yet, selecting best subset images a specific question can be difficult as sets vary along dimensions. In present report, we...
Spontaneous fluctuations of neural activity may explain why sensory responses vary across repeated presentations the same physical stimulus. To test this hypothesis, we recorded electroencephalography in humans during stimulation with identical visual stimuli and analyzed how prestimulus oscillations modulate different stages processing reflected by distinct components event-related potential (ERP). We found that strong alpha- beta-band power resulted a suppression early ERP (C1 N150) an...
The ongoing state of the brain radically affects how it processes sensory information. How does this activity interact with processing external stimuli? Spontaneous oscillations in alpha range are thought to inhibit processing, but little is known about psychophysical mechanisms inhibition. We recorded EEG while human observers performed a visual detection task stimuli different contrast intensities. To move beyond qualitative description, we formally compared psychometric functions obtained...
There is growing awareness across the neuroscience community that replicability of findings about relationship between brain activity and cognitive phenomena can be improved by conducting studies with high statistical power adhere to well-defined standardised analysis pipelines. Inspired recent efforts from psychological sciences, desire examine some foundational using electroencephalography (EEG), we have launched #EEGManyLabs, a large-scale international collaborative replication effort....
Abstract Perceiving an external stimulus depends not only on the physical features of stimulus, but also fundamentally current state neuronal excitability, indexed by power ongoing alpha-band and beta-band oscillations (8–30 Hz). Recent studies suggest that heightened excitability does improve perceptual precision, biases observers to report presence a regardless its presence. It is unknown whether this bias due changes in observers’ subjective experience (perceptual bias) or their...
Any large dataset can be analyzed in a number of ways, and it is possible that the use different analysis strategies will lead to results conclusions. One way assess whether obtained depend on strategy chosen employ multiple analysts leave each them free follow their own approach. Here, we present consensus-based guidance for conducting reporting such multi-analyst studies, discuss how broader adoption approach has potential strengthen robustness conclusions from analyses datasets basic...
Human brain activity in the gamma frequency range has been shown to be a correlate of numerous cognitive functions like attention, perception and memory access. More specifically, found enhanced when stimuli are stored or match with short-term (STM). We tested hypothesis that is also evoked representations long-term-memory (LTM). EEG was recorded from 13 subjects performing choice reaction task. Visual were either known real-world objects representation novel configurations never seen...
The phase and frequency of neural oscillations in the alpha band (8-12 Hz) have been recently proposed as key parameters for temporal resolution visual perception. Here, we tested possible causal links between these oscillatory features integration/segregation. individual (IAF) peak obtained from resting-state electroencephalography was used to set sensory (audio-visual) entrainment lower (IAF - 2 upper + alpha. Entrainment at IAF ± Hz administered prestimulus interval align a faster or...
Abstract Only small amounts of visual information, as determined by the capacity working memory, can be held in an active and accessible state. Thus, it is important to select maintain information that relevant while ignoring irrelevant information. However, underlying neural mechanism these processes has yet identified. One potential candidate are alpha oscillations (8–14 Hz), which have been shown inhibit stimulus processing perceptual tasks. During memory maintenance, power increases with...
Recent studies from the field of interoception have highlighted link between bodily and neural rhythms during action, perception, cognition. The mechanisms underlying functional body-brain coupling, however, are poorly understood, as ways in which they modulate behavior. We acquired respiration human magnetoencephalography data a near-threshold spatial detection task to investigate trivariate relationship respiration, excitability, performance. Respiration was found significantly perceptual...
Accumulating evidence suggests that visual perception operates in an oscillatory fashion at alpha frequency (around 10 Hz). Moreover, attention also seems to operate rhythmically, albeit a theta 5 Both rhythms are often associated "perceptual snapshots" taken the favorable phases of these rhythms. However, less is known about unfavorable phases: do they constitute "blind gaps," requiring observer guess, or information sampled with reduced precision insufficient for task demands? As simple...
