Special Electrophysiological Tests: Brain Spiking, EEG Spectral Coherence

Abstract

Largely as a consequence of advances in computer technology, the use of time series analysis methodology to investigate correlations of brain electrical activity with clinical disorders has become an area of intense effort in many EEG Research laboratories. The primary objective of many of these investigations is the detection of EEG time series properties which offer a quantitative basis for aiding diagnosis of mental illness or brain injury. This chapter describes the special electrophysiologic tests we have been developing at the Texas Research Institute of Mental Science (TRIMS) for use in research concerned with detecting EEG properties which correlate with particular abnormalities such as uncontrolled violent behavior, learning disabilities, and epilepsy.
