The Electroencephalogram (EEG) is a biological signal that represents the electrical activity of the brain. Artifacts in EEG signals are caused by various factors, like line interference, EOG (electro-oculogram) and ECG (electrocardiogram). The removal of artifact from scalp EEGs is of considerable importance for analysis of underlying brainwave activity. The presence of artifacts such as muscl...

Background and Purpose We examined metabolic and functional changes when forebrain ischemia was induced in strokeprone spontaneously hypertensive rats by bilateral carotid artery occlusion. In addition, the protective effect of clentiazem was evaluated in this model. Methods Rats were anesthetized with urethane. Cerebral blood flow was measured with a laser Doppler fkrwmeter. Cerebral high-ener...

BACKGROUND Processed electroencephalographic indices, such as the bispectral index (BIS), are potential adjuncts for assessing anesthetic depth. While BIS® monitors might aid anesthetic management, unprocessed or nonproprietary electroencephalographic data may be a rich source of information for clinicians. We hypothesized that anesthesiologists, after training in electroencephalography interpr...

OBJECTIVES It remains uncertain whether nonconvulsive seizures and nonconvulsive status epilepticus in pediatric traumatic brain injury are deleterious to the brain and/or impact the recovery from injury. Consequently, optimal electroencephalographic surveillance and management is unknown. We aimed to determine specialists' opinion regarding the detection and treatment of nonconvulsive seizures...

OBJECTIVE To test the hypothesis that treatment with cefepime hydrochloride leads to higher incidence of periodic epileptiform discharges compared with treatment with other β-lactams. DESIGN Data from hospital pharmacy databases of patients treated with cefepime or meropenem during a 42-month period (from January 1, 2007, through June 30, 2010) were retrospectively crossed with data from the ...

Amphetamine-like stimulants exert well-known arousal-enhancing actions. Surprisingly, little is known concerning the neuroanatomical substrates through which these drugs enhance arousal. Previous work implicates a number of basal forebrain structures in the regulation of behavioral state. The current studies examined the effects of amphetamine infusions made directly within basal forebrain site...

Sleep quality is related to people’s physical and mental health, so an accurate assessment of sleep key recognizing disorders taking effective interventions. To address the shortcomings traditional manual automatic staging methods, such as being time-consuming having low classification accuracy, method based on null space pursuit (NSP) decomposition algorithm single-channel electroencephalograp...

Cerebral palsy is a group of developmental disorders that affects certain percentage population motivating the development several types therapies ranging from conventional where physical are included to some alternative such as dolphin-assisted (DAT), in order improve quality life patients suffering these disorders. To find scientific evidence DAT effectiveness, this work developed four-stage ...

sclerosing leukoencephalitis of van bogaert is a fatal illness with characteristic clinical picture and electroencephalographic findings. although a viral or a immunological ctiology is suggested the exact cause remains.
