Investigating the roles of reflexes and central pattern generators in the control and modulation of human locomotion using a physiologically plausible neuromechanical model

Auke Ijspeert, Andrea Di Russo, Dimitar Yuriev Stanev, Anushree Bapusaheb Sabnis, Stéphane Armand

Objective. Studying the neural components regulating movement in human locomotion is obstructed by the inability to perform invasive experimental recording in the human neural circuits. Neuromechanical simulations can provide insights by modeling the locom ...

Investigating the neuromechanical control of healthy gait modulation and pathological gaits observed in cerebral palsy using neuromuscular simulations

Andrea Di Russo

Locomotion is based on a sophisticated interaction among the environment, the musculoskeletal system, the spinal cord, and the brain locomotor areas. Quality of life is strongly related to the proper capability of this movement. However, many pathologies, ...

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

Auke Ijspeert, Andrea Di Russo, Dimitar Yuriev Stanev, Stéphane Armand

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 (Central ...

Darwinian Dynamics of Embodied Chaotic Exploration

Joshua Evan Auerbach

We present Embodied Chaotic Exploration (ECE), a novel direction of research into a possible candidate for Darwinian neural dynamics, where such dynamics are occurring not at the level of synaptic connections, but rather at the slightly higher and more abs ...

Undirected compensatory plasticity contributes to neuronal dysfunction after severe spinal cord injury

Grégoire Courtine, Quentin Barraud, Pavel Musienko, Rubia van den Brand, Lucia Florinda Friedli Wittler, Janine Beauparlant

Severe spinal cord injury in humans leads to a progressive neuronal dysfunction in the chronic stage of the injury. This dysfunction is characterized by premature exhaustion of muscle activity during assisted locomotion, which is associated with the emerge ...

Self-Organization of Spinal Reflexes through Soft Musculoskeletal Interactions

There has been a long-standing debate on the question of how basic reflexive behaviours in mammals come about. Recently, it has been hypothesized that soft musculoskeletal interactions, such as intrinsic passive dynamics, might play a crucial role in the d ...

Somatosensory control of balance during locomotion in decerebrated cat

Grégoire Courtine, Pavel Musienko

Postmammillary decerebrated cats can generate stepping on a moving treadmill belt when the brain stem or spinal cord is stimulated tonically and the hindquarters are supported both vertically and laterally. While adequate propulsion seems to be generated b ...

Spinal cord reflexes induced by epidural spinal cord stimulation in normal awake rats

Grégoire Courtine

Motor responses in hindlimb muscles to epidural spinal cord stimulation in normal awake rats during bipedal standing were studied. Stimulation at L2 or S1 induced simultaneous and bilateral responses in the vastus lateralis, semitendinosus, tibialis anteri ...

Reflex movements for a virtual human: a biology inspired approach

Daniel Thalmann, Frédéric Vexo

This paper presents the results of a method to produce autonomous animation of virtual humans. In particular, the proposed methodology is focused on the autonomous synthesis of nonvoluntary gestures such as reflexes and subtle movements which provide a not ...

Neck Muscle Vibration and Spatial Orientation During Stepping in Place in Humans

Grégoire Courtine

Unilateral long-lasting vibration was applied to the sternomastoid muscle to assess the influence of asymmetric neck proprioceptive input on body orientation during stepping-in-place. Blindfolded subjects performed 3 sequences of 3 trials, each lasting 60 ...
