Sample text

Should the non-gaussian descriptors be excluded from the database? Even ignoring this problem, we will be left with a normative database in which accuracy is different for each descriptor. In fact, we have shown that the accuracy is a function of skewness and each approximation to gaussianity will lead to different skewness levels. Furthermore. the outcome of the Marco Congedo and Joel F. Luhar 27 normative database will be different on the two sides ofthe distribution. These are not desirable characteristics for a normative database.

Quantitative electroencephalography (qEEG) analysis incorporating the use of normative or reference database comparison has developed from being primarily a research tool into an increasingly widely used method for clinical neurophysiological evaluation. Method. A survey of several of the most widely used qEEG databases as well as issues surrounding the construction and use of these databases is presented, comparing and contrasting the various features of these databases, followed by a discussion of critical issues in this developing technology.

The weakness of this flexibility is in missing or inadvertently trivializing a phenomenon, or even creating a false image in the EEG if the reference selected is not a relatively neutral area electrically. An example is when strong temporal alpha contaminates the mastoid due to the lateral spread of the EEG through the skull. Thus, the ear references when contaminated create false alpha, displaced to areas Jack Johnstone and Jay Gunkelman 39 without alpha by the differential amplification system, which is blind as to the source of an oscillation, whether grid 1 or the reference at grid 2, the EEG output is an oscillation (see Gunkelman, 2000).
