Use of transcutaneous spinal cord stimulation to explore inhibitory and facilitatory circuits in muscles of the human lower limb. [PDF]

open access: yesExp Physiol
Abstract The aim of this study was to explore the primary afferent depolarization mechanism, to determine whether the soleus transspinal evoked potential (TEP), elicited through transcutaneous spinal cord stimulation over the L1–L2 level, is modulated by presynaptic inhibition and heteronymous facilitation, similar to the Hoffmann (H) reflex, elicited ...

Evidence that the cortical motor command for the initiation of dynamic plantarflexion consists of excitation followed by inhibition. [PDF]

open access: yesPLoS ONE, 2011
At the onset of dynamic movements excitation of the motor cortex (M1) is spatially restricted to areas representing the involved muscles whereas adjacent areas are inhibited.

Synaptic symphony: orchestration of an explicit monosynaptic reflex arc for autonomous movements in a biorobotic leg

open access: yesnpj Robotics
The reflex arc is fundamental to the physiology of posture and robust locomotion. Mimicking biological reflexes in engineered systems has, therefore, high potential to improve robustness and learning performance, especially when controlling humanoid ...

ATHLETIC: An exoskeleton countermeasure exercise device for resistive and plyometric training in deep‐space missions

open access: yesExperimental Physiology, EarlyView.
Abstract Prolonged exposure to weightlessness leads to loss of muscle and bone mass. Therefore, astronauts on board the International Space Station (ISS) currently perform mandatory daily exercises. ISS missions usually last 6 months, and future missions will become significantly longer when going, for example, to Mars.

Short-term plasticity in a monosynaptic reflex pathway to forearm muscles after continuous robot-assisted passive stepping

open access: yesFrontiers in Human Neuroscience, 2016
Both active and passive rhythmic limb movements reduce the amplitude of spinal cord Hoffmann (H-) reflexes in muscles of moving and distant limbs. This could have clinical utility in remote modulation of the pathologically hyperactive reflexes found in ...

Ipsi- and Contralateral Oligo- and Polysynaptic Reflexes in Humans Revealed by Low-Frequency Epidural Electrical Stimulation of the Lumbar Spinal Cord

open access: yesBrain Sciences, 2021
Epidural electrical stimulation (EES) applied over the human lumbosacral spinal cord provides access to afferent fibers from virtually all lower-extremity nerves.

Dynamic memory in rodent C‐fibres and its impact on spinal nociceptive processing

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Nociceptive C‐fibres display activity‐dependent slowing (ADS) whereby successive action potentials are conducted progressively slower thus regulating the temporal relay of pain signals. This study shows that the ADS induced by short stimulus trains (which mimic stimulus evoked firing, shown in orange) is modified by prior ...

Age‐Related Differences in Corticospinal Function and Muscle Strength: A Systematic Review and Meta‐Analysis

open access: yesEuropean Journal of Neuroscience, Volume 64, Issue 3, August 2026.
Changes in nervous system with age are responsible for reduced muscle force‐generating capacity (i.e., MVC). This meta‐analysis reveals that older adults exhibited lower resting corticospinal excitability and ICF, coupled with prolonged CSP and lower MVC, compared to younger adults.

Sensor-Motor Maps for Describing Linear Reflex Composition in Hopping

open access: yesFrontiers in Computational Neuroscience, 2017
In human and animal motor control several sensory organs contribute to a network of sensory pathways modulating the motion depending on the task and the phase of execution to generate daily motor tasks such as locomotion.

Delayed Onset Muscle Soreness and Critical Neural Microdamage-Derived Neuroinflammation

open access: yesBiomolecules, 2022
Piezo2 transmembrane excitatory mechanosensitive ion channels were identified as the principal mechanotransduction channels for proprioception. Recently, it was postulated that Piezo2 channels could be acutely microdamaged on an autologous basis at ...
