Cutaneous inputs to dorsal column nuclei in adult macaque monkeys subjected to unilateral lesion of the primary motor cortex or of the cervical spinal cord and treatments promoting axonal growth

Savidan, Julie ; Beaud, Marie-Laure ; Rouiller, Eric M.

In: Neuroscience Insights, 2020, vol. 15, p. 2633105520973991

The highly interconnected somatosensory and motor systems are subjected to connectivity changes at close or remote locations following a central nervous system injury. What is the impact of unilateral injury of the primary motor cortex (hand area; MCI) or of the cervical cord (hemisection at C7-C8 level; SCI) on the primary somatosensory (cutaneous) inputs to the dorsal column nuclei (DCN) in...

Spatiotemporal maps of proprioceptive inputs to the cervical spinal cord during three-dimensional reaching and grasping

Kibleur, Pierre ; Tata, Shravan R. ; Greiner, Nathan ; Conti, Sara ; Barra, Beatrice ; Zhuang, Katie ; Kaeser, Melanie ; Ijspeert , Auke ; Capogrosso, Marco

Proprioceptive feedback is a critical component of voluntary movement planning and execution. Neuroprosthetic technologies aiming at restoring movement must interact with it to restore accurate motor control. Optimization and design of such technologies depends on the availability of quantitative insights into the neural dynamics of proprioceptive afferents during functional movements....
