The quantitative analysis of the electroencephalogram (EEG) relies heavily on methods of time series analysis. A quantitative approach seems indispensable for research (be it clinical or basic neurophysical research), but it can also be a useful information for purely clinical purposes.

Electroencephalography and Clinical Neurophysiology, 1964
Abstract 1.1. EEG records and clinical observations were obtained from a population of 1264 subjects (age 15–45) comprising 1198 patients and 66 normal adult volunteers. In the clinical group 202 patients were diagnosed as suffering from migraine, using the criteria of Dow and Whitty (1947).

EEG coherence or EEG correlation?
International Journal of Psychophysiology, 1996In view of the widespread use of electroencephalographic correlation (r) and coherence (Coh) analyses in studying brain functional relationships, it seems important to illustrate results yielded by both methods. Although they are considered as equivalent, they show important differences.

Paediatrics and Child Health, 2018
Abstract A routine or standard Electroencephalography (EEG) study is frequently requested by paediatricians to aid diagnosis of epilepsy in children presenting with episodic behaviours. EEG study in children is significantly more sensitive if it includes a period of sleep. It is a valuable investigation provided it is considered in the context of good

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.

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 ...

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.
