Double discharges in human soleus muscle.

摘要: Double discharges (doublets) were recorded from human soleus, where they have never been found before. The data analyzed in this study collected 12 healthy volunteers. subjects recruited for other studies, concerning: (1) estimation of motoneurons’ afterhyperpolarization duration and (2) analysis motor unit responses to nerve stimulation, not trained voluntarily evoke doublets. majority doublet intervals fell into the commonly accepted range 2–20 ms. However, two soleus motoneurons one subject presented exceptional doublets interval about 37 This was virtually identical with between second third discharge few triplets another subject. It is hypothesized that are generated by delayed depolarization narrow hump, which same as hump responsible
