Abstract: The present study proposes to apply magnitude-squared coherence (MSC) to the somatosensory evoked potential for identifying the maximum driving response band. EEG signals, leads [Fpz'-Cz'] and [C3'-C4'], were collected from two groups of normal volunteers, stimulated at the rate of 4.91 (G1: 26 volunteers) and 5.13 Hz (G2: 18 volunteers). About 1400 stimuli were applied to the right tibial nerve at the motor threshold level. After applying the anti-aliasing filter, the signals were digitized and then further … Show more

“…The tSEP has been widely used for monitoring purposes (1,(16)(17)(18) and the ORD techniques are considered a promising tool for response detection (2,15,19) with a constant false-alarm rate defined a priori. However, the most suitable recording leads for tSEP is still an object of discussion.…”

“…Finally, the frequencies with best detection rates were the same reported by Infantosi et al (2006) and Melges et al (2012b), which used uni and multivariate ORD.…”

“…Moreover, a Tukey window with rising (and falling) time of 7 ms was employed to minimize spectral leakage. Epochs with high amplitude artifacts were discarded by an algorithm described in Infantosi et al (2006). crit were calculated using expressions (9), (10), (14) and (15) respectively, with M = 240, 120, 60 and 30 epochs and α = 5%.…”
