A Re-evaluation of Whether Non-monosynaptic Homonymous H Reflex Facilitation Tests Propriospinal Circuits
Autor: Karen M. Fisher, Stuart N. Baker
Publikováno v: Frontiers in Systems Neuroscience, Vol 15 (2021)
The C3–C4 propriospinal system is an important pathway mediating movement in cats; it contributes to movements in primates (including humans), and may have a role in recovery after lesion. Validated clinical tests of this system would find many app

Small sensory spinal lesions that affect hand function in monkeys greatly alter primary afferent and motor neuron connections in the cord
Autor: Karen M. Fisher, Joseph P. Garner, Corinna Darian‐Smith
Publikováno v: Journal of Comparative Neurology. 530:3039-3055
Small sensory spinal injuries induce plasticity across the neuraxis, but little is understood about their effect on segmental connections or motor neuron (MN) function. Here, we begin to address this at two levels. First, we compared afferent input d

Extensive Cortical Convergence to Primate Reticulospinal Pathways
Autor: Boubker Zaaimi, Karen M. Fisher, Stuart N. Baker, Steve A. Edgley
Publikováno v: The Journal of Neuroscience
Early evolution of the motor cortex included development of connections to brainstem reticulospinal neurons; these projections persist in primates. In this study, we examined the organization of corticoreticular connections in five macaque monkeys (o

Extensive somatosensory and motor corticospinal sprouting occurs following a central dorsal column lesion in monkeys
Autor: Karen M. Fisher, Joseph P. Garner, Corinna Darian-Smith, Alayna Lilak
Publikováno v: Journal of Comparative Neurology. 526:2373-2387
The corticospinal tract (CST) forms the major descending pathway mediating voluntary hand movements in primates, and originates from ∼nine cortical subdivisions in the macaque. While the terminals of spared motor CST axons are known to sprout local

Somatosensory System Organization in Mammals and Response to Spinal Injury
Autor: Corinna Darian-Smith, Karen M. Fisher
Spinal cord injury (SCI) affects well over a million people in the United States alone, and its personal and societal costs are huge. This article provides a current overview of the organization of somatosensory and motor pathways, in the context of

Reorganization of the Primate Dorsal Horn in Response to a Deafferentation Lesion Affecting Hand Function
Autor: Joseph P. Garner, Corinna Darian-Smith, Karen M. Fisher
Publikováno v: J Neurosci
The loss of sensory input following a spinal deafferentation injury can be debilitating, and this is especially true in primates when the hand is involved. While significant recovery of function occurs, little is currently understood about the reorga
