“…Clinical studies have shown that SSEP can be used both to identify dominant intercostal arteries and to determine if these vessels require re-implantation. 32 However, SSEP does not record motor function because perfusion of the anterior corticospinal tract is not assessed. Therefore, SSEP can be associated with delayed detection of ischaemia, thereby reducing its specificity.…”

“…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.…”

The objective of the present study was to determine the adequate cortical regions based on the signal-to-noise ratio (SNR) for somatosensory evoked potential (SEP) recording. This investigation was carried out using magnitude-squared coherence (MSC), a frequency domain objective response detection technique. Electroencephalographic signals were collected (International 10-20 System) from 38 volunteers, without history of neurological pathology, during somatosensory stimulation. Stimuli were applied to the right posterior tibial nerve at the rate of 5 Hz and intensity slightly above the motor threshold. Response detection was based on rejecting the null hypothesis of response absence (significance level α = 0.05 and M = 500 epochs). The best detection rates (maximum percentage of volunteers for whom the response was detected for the frequencies between 4.8 and 72 Hz) were obtained for the parietal and central leads mid-sagittal and ipsilateral to the stimulated leg: C4 (87%), P4 (82%), Cz (89%), and Pz (89%). The P37-N45 time-components of the SEP can also be observed in these leads. The other leads, including the central and parietal contralateral and the frontal and fronto-polar leads, presented low detection capacity. If only contralateral leads were considered, the centro-parietal region (C3 and P3) was among the best regions for response detection, presenting a correspondent well-defined N37; however, this was not observed in some volunteers. The results of the present study showed that the central and parietal regions, especially sagittal and ipsilateral to the stimuli, presented the best SNR in the gamma range. Furthermore, these findings suggest that the MSC can be a useful tool for monitoring purposes.

“…SEP monitoring has been used for 30 years [15]. It offers the promise of being able to avert neurological compromise by the early detection of abnormal signal transmission from distal extremities to the cerebral cortex [7]. But SEP is considered to only reflect conduction of sensory information in the posterior column, which is not as sensitive to the ischemia processes as the anterior pathway [11].…”
