Current practice of clinical electroencephalography

Guideline 4: standards of practice in clinical electroencephalography.

Current trends in electroencephalography.

Several recent articles re-emphasize the value of clinical electrophysiology: in localizing epileptogenesis, predicting effectiveness of epilepsy surgery, and disclosing a mechanism of benign Rolandic epilepsy of childhood.A review of the role of EEG in the diagnosis of epilepsy indicated that epileptiform activity will appear in 50% of initial awake recordings of adults with epilepsy and in 85...

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...

Clinical Electroencephalography for Anesthesiologists

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...

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,...
