Incremental embodied chaotic exploration of self-organized motor behaviors with proprioceptor adaptation [PDF]

, 2015
This paper presents a general and fully dynamic embodied artificial neural system, which incrementally explores and learns motor behaviors through an integrated combination of chaotic search and reflex learning.

Pre- and Post-alpha Motoneuronal Control of the Soleus H-reflex during Sinusoidal Hip Movements in Human Spinal Cord Injury [PDF]

, 2006
The aim of this study was to establish the contribution of hip-mediated sensory feedback to spinal interneuronal circuits during dynamic conditions in people with incomplete spinal cord injury (SCI).

Alcohol‐induced altered glycans in human tracheal epithelial cells promote bacterial adhesion

FEBS Open Bio, EarlyView.
Alcohol induces altered glycans to promote bacteria adhesion. Heavy alcohol drinking is known to increase the risk of bacterial pneumonia. However, the link between alcohol levels and risk of infection remains underexplored. Recently, we found that alcohol induced α2‐6sialo mucin O‐glycans in human tracheobronchial epithelial cells, which mediated the ...

Modulation of Stretch Reflexes of the Finger Flexors by Sensory Feedback from the Proximal Upper Limb Poststroke [PDF]

, 2006
Neural coupling of proximal and distal upper limb segments may have functional implications in the recovery of hemiparesis after stroke. The goal of the present study was to investigate whether the stretch reflex response magnitude of spastic finger ...

Strategies to augment volitional and reflex function may improve locomotor capacity following incomplete spinal cord injury [PDF]

, 2018
Many studies highlight the remarkable plasticity demonstrated by spinal circuits following an incomplete spinal cord injury (SCI). Such plasticity can contribute to improvements in volitional motor recovery, such as walking function, although similar ...

Interactions between stretch and startle reflexes produce task-appropriate rapid postural reactions

Frontiers in Integrative Neuroscience, 2015
Neural pathways underpinning startle reflex and limb stretch reflexes evolved independently and have served vastly different purposes. In their most basic form, the pathways responsible for these reflex responses are relatively simple processing units ...

Sensory modulation of gait characteristics in human locomotion: A neuromusculoskeletal modeling study.

PLoS Computational Biology, 2021
The central nervous system of humans and other animals modulates spinal cord activity to achieve several locomotion behaviors. Previous neuromechanical models investigated the modulation of human gait changing selected parameters belonging to CPGs ...

Visual Recovery Reflects Cortical MeCP2 Sensitivity in Rett Syndrome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Rett syndrome (RTT) is a devastating neurodevelopmental disorder with developmental regression affecting motor, sensory, and cognitive functions. Sensory disruptions contribute to the complex behavioral and cognitive difficulties and represent an important target for therapeutic interventions.

The Effects of Acute Lipopolysaccharide Induced Inflammation on Spinal Cord Excitability [PDF]

, 2018
Peripheral inflammation alters the excitability of dorsal horn interneurons and increases flexor reflex strength (Dubner & Ruda, 1992); however, its effect on the spinal stretch reflex is not well understood. The stretch reflex is a muscle contraction in

Long-Term Plasticity in Reflex Excitability Induced by Five Weeks of Arm and Leg Cycling Training after Stroke

Brain Sciences, 2016
Neural connections remain partially viable after stroke, and access to these residual connections provides a substrate for training-induced plasticity. The objective of this project was to test if reflex excitability could be modified with arm and leg (A
