Abstract: The natural flight response in shrimp is powered by rapid contractions of the abdominal muscle fibres to propel themselves backwards away from perceived danger. This muscle contraction is dependent on repetitive depolarization of muscle plasma… read more here.

DOI: 10.1109/access.2021.3078644
Abstract: We analyzed muscle excitation estimation systematically by Non-negative matrix factorization (NMF) from surface electromyograms (EMG) during dynamic contractions of biceps brachii (BB) muscles. We used motor unit action potentials (MUAPs) estimated experimentally from surface EMGs… read more here.

DOI: 10.1249/jes.0000000000000240
Abstract: Summary for table of contents: This article advances the hypothesis that a single, surface electromyogram may be of limited validity for the assessment of muscle excitation. When sampling electromyograms (EMGs) with one pair of electrodes,… read more here.
