概要	In this study, we performed simultaneous measurement of concentric bipolar active electrode (CBAE) and microneurography (MNG), which is an invasive measurement method, to compare noninvasive measurement of sympathetic nerve action potentials with actual nerve activities. Electrical stimulation tests performed on four male subjects showed burst waveforms similar to MNG in two subjects. In a Valsalva test conducted on three male subjects, two persons measured waveforms synchronized with the MNG burst waveform. These results indicate that, although with low spatial resolution, CBAE may be able to directly measure non-invasive sympathetic electrical activity.
