Optimal feedback control and the long-latency stretch response

JA Pruszynski, SH Scott - Experimental brain research, 2012 - Springer
There has traditionally been a separation between voluntary control processes and the fast
feedback responses which follow mechanical perturbations (ie, stretch “reflexes”). However …

Long-latency reflexes account for limb biomechanics through several supraspinal pathways

IL Kurtzer - Frontiers in integrative neuroscience, 2015 - frontiersin.org
Accurate control of body posture is enforced by a multitude of corrective actions operating
over a range of time scales. The earliest correction is the short-latency reflex (SLR) which …

F Asci, M Falletti, A Zampogna, M Patera, M Hallett… - Brain, 2023 - academic.oup.com
Although rigidity is a cardinal motor sign in patients with Parkinson's disease (PD), the
instrumental measurement of this clinical phenomenon is largely lacking, and its …

Control of wrist position and muscle relaxation by shifting spatial frames of reference for motoneuronal recruitment: possible involvement of corticospinal pathways

H Raptis, L Burtet, R Forget… - The Journal of …, 2010 - Wiley Online Library
It has previously been established that muscles become active in response to deviations
from a threshold (referent) position of the body or its segments, and that intentional motor …

Learning new feedforward motor commands based on feedback responses

RS Maeda, PL Gribble, JA Pruszynski - Current Biology, 2020 - cell.com
Learning a new motor task modifies feedforward (ie, voluntary) motor commands and such
learning also changes the sensitivity of feedback responses (ie, reflexes) to mechanical …
