Awake state-specific suppression of primary somatosensory evoked response correlated with duration of temporal lobe epilepsy

Abstract: Epilepsy is a network disease. The primary somatosensory cortex (S1) is usually considered to be intact, but could be subclinically disturbed based on abnormal functional connectivity in patients with temporal lobe epilepsy (TLE). We aimed to investigate if the S1 of TLE is abnormally modulated. Somatosensory evoked magnetic fields (SEFs) evoked by median nerve stimulation were recorded in each hemisphere of 15 TLE patients and 28 normal subjects. All responses were separately averaged in the awake state and l… Show more

“…In SEF measurements using SQUID sensors with similar filter conditions, the maximum M20 amplitude was approximately 300 fT [14], [16]- [18]. The amplitude of 725 fT (519-1,134 fT) in this study was larger than that of the SEF measurements using SQUID sensors.…”

“…We have already reported successful measurement of chest-attached magnetocardiography (MCG) without signal averaging techniques and scalp-attached MEG of the alpha wave, awake brain background rhythm, by signal averaging techniques 10 . Our combination of magnetic ux concentrators has nally reached to the sensitivity of the TMR sensor at the level of 940 fT/√Hz at 1 Hz and 50 fT/√Hz at 1 kHz, which are adequate to measure somatosensory evoked magnetic elds (SEFs), which are one of the weakest signals but used in most common applications of MEG [11][12][13][14] . Our present success with scalp-attached tangential MEG measurement will allow non-invasive imaging of human brain functions at millimeter and millisecond resolutions.…”
