DOI: 10.1093/cercor/bhad089
Abstract: Higher-level cognitive functions are mediated via complex oscillatory activity patterns and its analysis is dominating cognitive neuroscience research. However, besides oscillatory (period) activity, also aperiodic activity constitutes neural dynamics, but its relevance for higher-level cognitive… read more here.

DOI: 10.1093/scan/nsaf059
Abstract: Abstract In electroencephalography (EEG), action execution (AE) is reliably associated with reductions in the mu rhythm, a periodic oscillation (8–14 Hz) over sensorimotor cortex. Similar patterns of “mu suppression” have been reported during observations of others’… read more here.

DOI: 10.1101/2022.11.07.515423
Abstract: The power of electrophysiologically measured cortical activity decays with an approximately 1/fX function. The slope of this decay (i.e. the spectral exponent, X) is modulated by various factors such as age, cognitive states or psychiatric/neurological… read more here.

DOI: 10.3389/fnins.2025.1657792
Abstract: Introduction Disorders of consciousness (DoC), including unresponsive wakefulness syndrome (UWS) and minimally conscious state (MCS), are primarily diagnosed behaviorally. Recent evidence indicates that loss of consciousness manifests as irregularities in neural oscillatory activity across delta,… read more here.

DOI: 10.3390/biomedicines11061607
Abstract: Developmental Dyslexia (DD) is a neurobiological condition affecting the ability to read fluently and/or accurately. Analyzing resting-state electroencephalographic (EEG) activity in DD may provide a deeper characterization of the underlying pathophysiology and possible biomarkers. So… read more here.
