Syncope and electroencephalography

Electroencephalography

Recent advances in electroencephalography (EEG) research are presented. Particular emphasis is placed on sleep and epilepsy research in humans. In this context, among others, studies on the modifications of EEG epileptic activity during sleep are discussed in more detail. A large number of reports come from EEG monitoring during presurgical evaluation and surgical treatment of drug-resistant ep...

Electroencephalography and panic disorder

INTRODUCTION: Panic disorder is frequent psychiatric disorder characterized by sudden and unexpected onset of a panic attack, characterized by terror or impending doom, and associated with many somatic symptoms. METHODS: A literature review was performed using the National Library of Medicine PubMed database and Web of Science, including all resources within the period 1991–2011, additional ref...

Electroencephalography and Clinical Neurophysiology

Repetitive stimulation in midline and intralaminar regions of the thalamus causes widespread changes in ongoing cortical activity. Contrasting effects may be obtained from the same loci by low and high frequency stimulation. Thus, stimulation at 6-12/see produces recruiting responses (Morison and Dempsey 1942), whereas high frequency stimulation at the same recruiting sites induces low voltage,...

ELECTROENCEPHALOGRAPHY AND CLINICAL NEUROPHYSlOLOGY

The main focus of the self-stimulation phenomenon, as indicated by maximum rates for minimum stimulus levels and by lesion studies, iies in an olfactory midbrain pathway through septal area, lateral hypothalamus and ventrolateral tegmemum; over most of its course this pathway is called the medial forebrair bundle. The studies which indicated this "focus" also showed a gradient of self-stimulati...
