60-year-old woman was treated for a brain metastasis. the patient received intensity-modulated radiation therapy (sib-imrt) dose of 30 gy for the whole brain and 40 gy delivered simultaneously to individual brain metastases in 10 fractions. the present report investigated the influence of applied novel prepared treatment plan, among others the fractionation protocol on the electroencephalogram ...

An improved understanding of the neural correlates of altered arousal states is fundamental for precise brain state targeting in clinical settings. More specifically, electroencephalogram recordings are now increasingly being used to relate drug-specific oscillatory dynamics to clinically desired altered arousal states. Dexmedetomidine is an anesthetic adjunct typically administered in operatin...

8 January 2015 T HE electroencephalogram is the scalp recording of the electrical activity of the brain and reflects the activity of millions of neurons on and just below the surface of the brain. The electroencephalogram is used extensively as surrogate marker of anesthetic effect. The rhythmic pattern of the electroencephalogram is complex and while some patterns are easily recognized by the ...

The widely used electroencephalogram-based indices for depth-of-anesthesia monitoring assume that the same index value defines the same level of unconsciousness for all anesthetics. In contrast, we show that different anesthetics act at different molecular targets and neural circuits to produce distinct brain states that are readily visible in the electroencephalogram. We present a two-part rev...

This study aimed to identify the indications in which electroencephalography in the pediatric emergency department is most useful. We retrospectively reviewed the influence that the results of the emergent electroencephalogram had on the eventual disposition of patients at our pediatric emergency department. Sixty-eight children (mean age, 7.3 years; 32 males) underwent 70 emergent electroencep...
