Comparison of techniques for objective identification of EEG responses to somatosensitive stimulation

Abstract

Three different frequency-domain techniques, the Spectral F-Test (SFT), Component Synchrony Measure (CSM) and Magnitude-Squared Coherence (MSC) have been studied for the detection of responses in the EEG to repetitive somatosensitive stimulation (RSSS). In simulations, the three techniques were tested and the performance of the detectors compared. In real EEG data (approximately 10 second segments), spectral changes under RSSS at 4 and 8 Hz were found; CSM and MSC performed better than SFT, as was also found in simulations.
