Muscle length project

The aim of this project was to investigate whether whether alterations in muscle length could alter the common synaptic oscillations to spinal motor neurons, particularly in the tremor band (5-15 Hz). To achieve this, we decomposed motor unit spike trains from high-density surface electromyograms recorded from a leg muscle (tibialis anterior; TA) at two different muscle lengths using this algorithm. To interpret the results derived from the motor unit spike trains, we conducted a second set of experiments, combined with computational simulations, to investigate how changes in muscle length affected the low-pass characteristics of the TA twitches.For further details, please refers to the <b>READ ME</b> file.本研究旨在探究肌肉长度改变是否会影响脊髓运动神经元的共突触振荡，尤其是在震颤频段（5-15 Hz）内。为达成该研究目标，我们利用本算法，从两种不同肌肉长度下采集的腿部肌肉（胫骨前肌；TA）高密度表面肌电图（high-density surface electromyograms）信号中，分解得到了运动单位锋电位序列（motor unit spike trains）。为解读由运动单位锋电位序列得到的实验结果，我们开展了第二组实验并结合计算仿真，以探究肌肉长度变化如何影响TA抽搐的低通特性。如需获取更多详细信息，请参阅<b>READ ME</b>文件。
