In this study, our purpose is the development of measuring and monitoring system to investigate the brain activity in usual behavior without restraint. Using this system, we can obtain physiological information such as EEG, ECG and cerebral blood of the subject always and anywhere, even if subjects walk around or move freely. In this study, we applied this system to evaluate the concentration state...
This paper suggests possibility for detecting recruitment of fast muscle fiber on increasing load tests by multiresolution analysis of surface electromyograms (sEMGs). Recruitment of the muscle fiber can be guessed from a graph of power ratio vs. % maximum voluntary contraction concerning the detail at each level, RPD(j). RPD(j)s are extracted parameters from multiresolution analysis of sEMGs. The...
An alias-free sampling technique proposed by A.S. French and A.V. Holden (1971) is often applied to the analysis of neuronal spike trains. It is based on the integral pulse frequency modulation model and on a low-pass-filtering technique proposed by E.J. Bayley (1968). The authors recently improved the alias-free sampling technique, but when it was applied to isolated spike trains, its accuracy was...
