Brain activity abounds with rhythmic patterns (Capilla et al., 2021; Groppe 2013; Keitel & Gross, 2016) that reflect ongoing fluctuations of neuronal excitability (Adrian Matthews, 1934; Bishop, 1932). These rhythms can be described as oscillations cycle through phases at specific frequencies and a certain strength or amplitude (Figure 1). Attempts to account for the functional relevance have gone from associating cognitive function X Y more comprehensive understanding role brain in human everyday experience behaviour (Buzsáki Draguhn, 2004; Fries, 2015; Lakatos 2019; Wang, 2010). accounts support simple, yet fundamental idea: Cognitive functions themselves may intrinsically rhythmic.

We suspect this is associated form perception, partakes nature sweep rhythm, like process television apparatus." Theories derived these early ideas been reiterated over past 90 years. During time, research focussed on variations framework claiming processes depend offered wealth empirical evidence (Schroeder 2010; VanRullen, 2016; VanRullen Koch, 2003). Rhythmic sampling, implemented rhythms, proposed underlies not only perception but also attention (VanRullen 2007), memory (Staresina 2015), language (Giraud Poeppel, 2012). Linking cognition sampling particularly attractive because allows using global mechanistic principles bridge two different levels explanation: normal function, involves activity, experiences. addition, leaves open possibility actively intervening external stimulation either advance theory, example, close causal (see section 'Can we manipulate take control cognition?'), develop applications clinical interventions, such rehabilitation, brain-computer interfaces.

Electroencephalography (EEG) has shown potential for identifying early-stage biomarkers of neurocognitive dysfunction associated with dementia due to Alzheimer's disease (AD). A large body evidence shows that, compared healthy controls (HC), AD is power increases in lower EEG frequencies (delta and theta) decreases higher (alpha beta), together slowing the peak alpha frequency. However, pathophysiological processes underlying these changes remain unclear. For instance, recent studies have that apparent shifts from high low can be driven either by frequency specific periodic or rather non-oscillatory (aperiodic) 1/f slope spectrum. Hence, clarify mechanism(s) alterations AD, it necessary account both aperiodic characteristics signal. Across two independent datasets, we examined whether resting-state linked reflect true oscillatory (periodic) changes, (non-oscillatory) signal, a combination both. We found strong are purely nature, at beta (AD < HC) leading + beta) / ratios AD. Aperiodic features did not differ between HC. By replicating findings cohorts, provide robust pathophysiology against changes. therefore neural dynamics emphasize robustness signatures, which may further used as prognostic interventional targets future clinical investigations.

Abstract The brain organizes the continuous flow of sensory input by parsing it into discrete events. In case two flashes separated a brief ISI, for example, perception may be single flash or distinct flashes, depending on ISI but also speed processing. A number studies have reported evidence that participants with higher EEG peak alpha frequency are able to detect presence short intervals, whereas those slower report only one flash. Other not found this correlation. We investigated potential factors might mask relationship between individual and visual perception. recorded resting-state from large sample (n = 50) measured temporal resolution two-flash fusion task. over posterior channels predicted threshold, in line previous studies, correlation was significant when taking account steepness psychophysical curve Participants relatively shallow curve, likely reflecting high and/or decision noise, failed show relationship.

When exposed to rhythmic stimulation, the human brain displays activity across sensory modalities and regions. Given ubiquity of this phenomenon, how rhythms are transformed into neural remains surprisingly inconclusive. An influential model posits that endogenous oscillations entrain external rhythms, thereby encoding environmental dynamics shaping perception. However, research on entrainment faces multiple challenges, from ambiguous definitions methodological difficulties when need be identified disentangled other stimulus-related mechanisms can lead similar phase-locked responses. Yet, recent years have seen novel approaches overcome these including computational modeling, insights dynamical systems theory, sophisticated stimulus designs, study neuropsychological impairments.

In recent years, idea rhythmic perception has regained popularity, assuming that parieto-occipital alpha oscillations are neural mechanism defining rhythmicity visual perception. Consequently, behavioural response should also fluctuate rhythm (i.e., at ~ 10 Hz). To test this hypothesis, we employed integration task. Crucially investigated if subliminal stimulus preceding target modulates behaviour. Our results show behaviour fluctuates function delay between and stimuli.
