Inhibitory projections from pronator teres to biceps brachii motoneurones in human

Abstract: Neural projections from the pronator teres (PT) muscle to biceps brachii (BB) motoneurones were studied in three healthy human subjects using a post-stimulus time histogram method. In 25 BB motor units, electrical stimulation to the PT nerve with intramuscular needle electrodes induced inhibition in nine units (36%), whereas facilitation was produced in 18 units (72%) by stimulation to the median nerve trunk with surface electrodes at the distal end of the intermuscular septum of the arm or in the cubital foss… Show more

“…Facilitation and inhibition mediated by low threshold afferent fibers among muscles in the human upper limb have been studied (Baldissea et al 1983;Day et al 1984;Cavallari and Katz 1989;Katz et al 1991;Schieppati et al 1991;Cavallari et al 1992;Creange et al 1992;Rossi et al 1995;Aymard et al 1995;Naito et al 1996Naito et al , 1998aMarchard-Pauvert et al 2000;Naito 2003Naito , 2004aSuzuki et al 2005;Ogawa et al 2005;Wargon et al 2006;Sato et al 2006;Nakano et al 2006). The BB motoneurons receive monosynaptic facilitation of group Ia fibers from the extensor carpi radialis (ECR) and FCR, disynaptic inhibition of group Ia fibers from the triceps brachii (TB), and oligosynaptic inhibition of group I fibers from PT (Katz et al 1991;Cavallari et al 1992;Naito et al 1996, 1998a, Naito 2003, 2004a.…”
