Estimates of persistent inward currents in lower limb motoneurons are larger in females than in males

Autor: Sophia T. Jenz, James A. Beauchamp, Matheus M. Gomes, Francesco Negro, C. J. Heckman, Gregory E. P. Pearcey

Publikováno v: Journal of Neurophysiology. 129:1322-1333

Sex-related differences in motoneuron analyses have emerged with greater inclusion of female participants, however, mechanisms for these differences remain unclear. Estimates of persistent inward currents (i.e., Δ F) in motoneurons of the lower limb

A geometric approach to quantifying the neuromodulatory effects of persistent inward currents on single motor unit discharge patterns

Autor: James. A. Beauchamp, Gregory E. P. Pearcey, Obaid U. Khurram, Matthieu Chardon, Curtis Wang, Randall K. Powers, Julius P.A. Dewald, CJ. Heckman

ObjectiveAll motor commands flow through motoneurons, which entrain control of their innervated muscle fibers, forming a motor unit (MU). Owing to the high fidelity of action potentials within MUs, their discharge profiles detail the organization of

Antagonist tendon vibration dampens estimates of persistent inward currents in motor units of the human lower limb

Autor: Gregory E P Pearcey, Obaid U Khurram, James A Beauchamp, Francesco Negro, Charles J Heckman

We can readily measure motoneuron discharge patterns in humans due to the one-to-one spike relation between motoneuron and muscle fiber action potentials, which allows us to make inferences about motor commands. Persistent inward currents (PICs), whi

A computational approach for generating continuous estimates of motor unit discharge rates and visualizing population discharge characteristics

Autor: James A Beauchamp, Obaid U Khurram, Julius P A Dewald, CJ Heckman, Gregory E P Pearcey

Publikováno v: Journal of neural engineering. 19(1)

Objective. Successive improvements in high density surface electromyography and decomposition techniques have facilitated an increasing yield in decomposed motor unit (MU) spike times. Though these advancements enhance the generalizability of finding

Brass instruments as a cascade of two-port networks : Transfer functions, chain parameters, and power efficiency in theory and practice

Autor: Wilfried Kausel, James W. Beauchamp, Alexander Mayer

This paper investigates how two-port network theory as a means for system identification can be applied to the analysis of brass instruments. A special focus is placed on the energy conversion efficiency as this is limited by inner damping, which rec
