The aim of the work is an integration of contemporary electroencephalographic data on addictive disorders. A search in e-library, PubMed, EBSCO and Springer databases permitted us to define some of main directions (predisposition, effect of single intake, of dependence, abstinence, and role of comorbidities) and techniques (visual, spectral and coherence analysis, evoked potentials and oscillations) of investigations in that field. Methodology involved in the cited works was taken into account during the process of summarization of results.

Fluoxetine, but not paroxetine, alters the jaw-closing muscle activity during non-rapid eye movement sleep in mice.

Neurosci Res

Sleep bruxism is an involuntary, exaggerated jaw-closing activity during sleep. Selective serotonin reuptake inhibitor (SSRI) use is a risk factor for bruxism. However, the effect of various SSRIs on masseter (jaw-closing) muscle activity remains unclear.

Incidence of postoperative seizures in neonates following cardiac surgery with regional cerebral perfusion and deep hypothermic circulatory arrest.

JTCVS Open

December 2023

Division of Cardiac Critical Care Medicine, Department of Anesthesiology and Critical Care Medicine, Children's Hospital of Philadelphia, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, Pa.

Objectives: Historically, our center has primarily used deep hypothermic circulatory arrest, but in recent years some surgeons have selectively used regional cerebral perfusion as an alternative. We aimed to compare the incidence of postoperative electroencephalographic seizure incidence in neonates undergoing surgery with regional cerebral perfusion and deep hypothermic circulatory arrest.

Methods: A retrospective analysis was performed in neonates who underwent surgery between 2012 and 2022 with either deep hypothermic circulatory arrest or regional cerebral perfusion with routine postoperative continuous electroencephalography monitoring for 48 hours.

Continually emerging data indicate that sub-clinical, non-convulsive epileptiform activity is not only prevalent in Alzheimer's disease (AD) but is detectable early in the course of the disease and predicts cognitive decline in both humans and animal models. Epileptiform activity and other electroencephalographic (EEG) measures may hold powerful, untapped potential to improve the translational validity of AD-related biomarkers in model animals ranging from mice, to rats, and non-human primates. In this review, we will focus on studies of epileptiform activity, EEG slowing, and theta-gamma coupling in preclinical models, with particular focus on its role in cognitive decline and relevance to AD.

Background: Electroencephalographic (EEG) recordings are used to trace neural activity within the cortex to study brain functioning over time.

Introduction: During data acquisition, the unequivocal way to reduce artifact is to avoid artifact stimulating events. Though there are certain artifacts that make this task challenging due to their association with the internal human mechanism, in the human-computer interface, these physiological artifacts are of great assistance and act as a command signal for controlling a device or an application (communication).

The present electroencephalographic (EEG) study was designed to investigate the perception of Mandarin neutral tone (T0) by adult Mandarin speakers. For this purpose, we examined the event-related brain potential (ERP) correlates of T0 processing in two-character Mandarin compounds. Eighteen native Mandarin speakers were tested using a modified oddball paradigm.
