In order to explore an objective method to detect the mental fatigue and to investigate whether magnetic stimulation at acupoint can relieve mental fatigue, a model of mental fatigue was built by reading English scientific papers continuously for 4 hours in this study. The mismatch negativity (MMN) component of event-related potentials (ERPs) was extracted using auditory oddball paradigm as the evaluation...
Two acupuncture manipulations are clinically used: manual manipulation and electrical acupuncture. There is little published on the EEG changes during magnetic stimulation on an acupuncture site. In this study, EEG data in response to magnetic stimulation on HeGu (LI 4) acupoint were measured to determine whether magnetic acupoint stimulation might modulate ongoing EEG or not. Eighteen healthy volunteers...
Electrical impedance tomography (EIT) is a new functional imaging technique. This paper presents the development of a new electrical impedance tomography system with 128 electrodes for impedance change detection and 3D imaging of the human thorax. The system consists of several modules, including multi-frequency current source, driving, measuring, data acquisition, and controlling and signal processing...
Electrical impedance tomography (EIT) is a noninvasive technique that permits estimation of resistivity within a subject by reconstructing from boundary measurements. The head electrical properties based on EIT technology have been studied by many authors and in most of this work the realistic head model has been considered without contact impedance between the electrodes and the scalp. It is interesting...
