A system (10) includes multiple input channels (11, 12, 13, 14) for receiving physiological signals such as those from EEG, EMG, and EOG electrodes. The physiological signals are digitized in an analog to digital converter (15) and the digital data are supplied to compute controller which stores data and which, on the real time basis, performs the initial feature extraction, pattern detection and classification steps. The controller includes central processing unit (19) with associated storage means (20, 21, 26, 27, 28), display (CRT) (34), keyboard and/or mouse (31, 32). The system (10) gathers data over relatively long period of time and displays to a user a continuous updated analysis of the physiological information. The raw data is simultaneously stored for later retrieval. Upon the completion of the tests, the operator can interact with the system and ca re-analyse the data based on his judgments. |
