ABSTRACT:
An apparatus for performing manipulation and analysis of data characteristic of brain electrical activity of a patient. Computer analysis is utilized to provide the most useful form of topographical maps and related data for evaluation of a patient by a user. The application can be operated as part of an integral unit or remote from the location where brain electrical activity signals are measured on the patient.
Threshold circuitry ensures that only signals meeting predetermined conditions are stored. A user modifiable digital filter allows for on-line analysis of changes in filter characteristics. A simultaneaous display of a plurality of topographical maps in visual summary format is presented. Readability is enhanced by showing only the color codes that actually appear in the topographical map. Montages can be created.
