Topic: multiply innervated muscle fibers

Classically, oculomotor motoneurons (MNs) have been described as a single homogeneous group based on their firing pattern. However, recent anatomical and electrophysiological findings from our group suggest that there are subpopulations of neurons in these nuclei, i.e., those innervating single (SIF) and multiply innervated muscle fibers (MIF) differ in their neuronal sensitivity and recruitment order.​The diversity of MNs in the mature spinal cord has been extensively studied, revealing a variety of markers that identify subgroups, such as alpha, gamma, slow and fast fatigable, and fatigue-re
