Lower somatosensory evoked potential
WebNeuroanatomic substrates of these somatosensory evoked potential (SSEP) components are less well clarified compared with those of upper extremity (median nerve) SSEPs, primarily because clinical application of lower extremity SSEPs is more difficult, and all of the aforementioned potentials but one (P40) are not obligatory components. WebSomatosensory evoked potentials (SSEPs) have been used as indicators of cerebral ischemia during CEA, although far less commonly than EEG. In NASCET, 7% of patients were monitored with SSEPs.104 Unlike EEG, SSEPs are sensitive to …
