Electroencephalography and Clinical Neurophysiology, 1958
Abstract An apparatus is described providing for continuous display of 20 frequencies with a time resolving power of one second approximately. The spectrogram is directly visible on a cathode ray tube and is photographically recorded with another cathode ray tube. Spectrograms of various test signals are shown.

Electroencephalography and Clinical Neurophysiology, 1966
Abstract EEGs showed unspecific abnormal activity in 22% of 113 migrainous patients and in 24% of 76 patients suffering from psychogenic or tension headache. The small difference in the number of abnormal EEGs between the two samples appears to eliminate the EEG as an important diagnostic aid in the screening of common headache syndromes.

Publisher Summary Studies suggest that all forms of behavior are originated in and governed by the nervous system, and thus are the product of neuronal activity. Considering that all functional neuronal activity is accompanied by electrical phenomena of some kind or another, it has been concluded that all behavioral acts are reflected in the central ...

After more than 85 years of development and use in clinical practice, the electroencephalogram (EEG) remains a dependable, inexpensive, and useful diagnostic tool for the investigation of the electrophysiologic activity of the brain. The advent of digital technology has led to greater sophistication and multiple software applications to extend the ...

EEG is the best study for evaluating the electrophysiologic function of the brain. The relevance of EEG is based on an accurate interpretation of the recording. Understanding the neuroscientific basis for EEG is essential. The basis for recording and interpreting EEG is both brain site-specific and technique-dependent to detect and represent a complex ...

The Neurodiagnostic Journal, 2016
Coma is defined as a state of extreme unresponsiveness, in which a person exhibits no voluntary movement or behavior even to painful stimuli. The utilization of EEG for patients in coma has increased dramatically over the last few years. In fact, many institutions have set protocols for continuous EEG (cEEG) monitoring for patients in coma due to ...

Publisher Summary EEG is derived from wave activity of nerve cells in the cerebral cortex. The elementary generators of the EEG are relatively small patches of the cell membrane, including several synapses and some passive membrane through which the synaptic current returns into the cell.
