Research Abstract |
A prototype of concentric bipolar active (CBA) electrode with ultra-high input impedance was made. The CBA electrode, combined with a separately developed bio-amplifier with high common mode rejection ratio (CMRR), was investigated to measure muscle sympathetic nerve activity (MSNA) noninvasively from sciatic nerve at posterior region of knee. Simultaneous measurement of the proposed approach and invasive microneurography (MNG) was conducted. While intermittent MSNA bursts were observed clearly in the MNG recording, burst-like spike potentials in the recording of the proposed method were observed only after applying a modified Wavelet-based denoising. However, both activated periods were almost the same, and both peak values of the rectified and integrated bursts correlated each other.
