Hypsarrhythmia in West syndrome, although hard to define, is characterized by chaotic and disorganized electrical activity of the brain and is often regarded as a generalized EEG pattern without any localization value. Using event-related spectral perturbation (ERSP), we tried to determine the brain dynamics during hypsarrhythmia. Routine 1-h scalp EEGs were retrieved from 31 patients with infantile spasms and 20 age-matched controls. Using the EEGLAB toolbox of MATLAB 2015b, the ERSPs of fast oscillations (FOs; 20–100 Hz) of selected channels were analyzed and compared among groups according

Abstract Older adults with amnestic mild cognitive impairment (MCI) experience a decline in episodic memory but do not meet diagnostic criteria for dementia. Mounting evidence suggests other aspects of cognition may be impacted, including behavioral and neural alterations in conflict monitoring. Neural underpinnings of these changes have been captured through the use of electroencephalography (EEG) by most frequently examining event-related potentials (ERPs). Fewer studies have examined event-related spectral perturbations (ERSPs) that underlie conflict processes in MCI. We examined difference

Inhibitory control is an integral part of executive functions. In this study, we report event-related spectral perturbation (ERSP) results from 15 healthy adults performing an emotional stop-signal task with the use of happy, disgusted, and neutral emotional faces. Our ERSP results at the group level suggest that changes in low frequency oscillatory power for emotional and neutral conditions start at as early as 200 ms after stimulus onset and 300 ms before button press for successful go trials. To quantify the dynamics of trial-by-trial theta power, we applied the hierarchical drift diffusion

Sleep has been shown to promote memory consolidation driven by certain oscillatory patterns, such as sleep spindles. However, sleep does not consolidate all newly encoded information uniformly but rather “selects” certain memories for consolidation. It is assumed that such selection depends on salience tags attached to the new memories before sleep. However, little is known about the underlying neuronal processes reflecting presleep memory tagging. The current study sought to address the question of whether event-related changes in spectral theta power (theta ERSP) during presleep memory forma

Background: Event-related potentials (ERPs) are currently utilized to study information processing under the influence of neuropsychiatric disorders and are candidate endophenotypes of schizophrenia. However, the traditional ERP approach discards most oscillatory information in the EEG through grand averaging process. This study tried to focus on ERP component of mismatch negativity (MMN) between control and schizophrenia groups in Taiwan. In addition to traditional (grand average) ERP approach, we also compared the time-frequency analysis results of the mismatch negativity. Methods: MMN value

Abstract Resting state electroencephalography (EEG) activity captures spontaneous neural activity while at rest. Mounting evidence suggests that resting state EEG activity is linked to cognitive performance and event-related potentials in young adults. However, little is known on the relationship between resting state EEG activity and event-related spectral perturbations (ERSPs) and/or behavioral performance linked to inhibitory control in cognitively unimpaired older adults (OA). This study examined the relationship between resting state alpha power and 1) alpha-band ERSPs and 2) behavioral m

Much of the work in alpha NFT has focused on evaluating changes in alpha amplitude. However, the generation mechanism of training-induced alpha activity has not yet been clarified. The present study aimed to identify sources of training-induced alpha activity through four temporal/spectral analytic techniques, i.e., the max peak average (MPA), positive average (PA), negative average (NA) and event-related spectral perturbation average (ERSPA) methods. Thirty-five healthy participants were recruited into an alpha group receiving feedback of 8–12-Hz amplitudes, and twenty-eight healthy participa

Abstract This study examined (i) the stage at which pitch accents contribute to lexical processing in native Japanese speakers and (ii) the interpretation pathway for the meaning of words pronounced with incorrect pitch accents. Event-related potential analyses during spoken word processing showed that words with incorrect accents elicited greater N400 amplitudes than those with correct accents, indicating that accent information aids in selecting suitable candidates from activated lexicons rather than in lexical activation itself. We employed a cross-modal semantic priming paradigm for the se

Elements in speech and music unfold sequentially over time. To produce sentences and melodies quickly and accurately, individuals must plan upcoming sequence events, as well as monitor outcomes via auditory feedback. We investigated the neural correlates of sequential planning and monitoring processes by manipulating auditory feedback during music performance. Pianists performed isochronous melodies from memory at an initially cued rate while their electroencephalogram was recorded.

Planning goal-directed movements towards different targets is at the basis of common daily activities (e.g., reaching), involving visual, visuomotor, and sensorimotor brain areas. Alpha (8–13 Hz) and beta (13–30 Hz) oscillations are modulated during movement preparation and are implicated in correct motor functioning. However, how brain regions activate and interact during reaching tasks and how brain rhythms are functionally involved in these interactions is still limitedly explored. Here, alpha and beta brain activity and connectivity during reaching preparation are investigated at EEG-sourc

If its neural correlates were better understood, it would provide a useful assay and target for neurorehabilitation for people with impaired proprioception.
