Suboptimal muscle synergy activation patterns generalize their motor function across postures
Frontiers in Computational Neuroscience, 2016 We used a musculoskeletal model to investigate the possible biomechanical and neural bases of using consistent muscle synergy patterns to produce functional motor outputs across different biomechanical conditions, which we define as generalizability ...

Dopamine Modulates Ih in a Motor Axon [PDF]
Journal of Neuroscience, 2010 We studied the axons of the pyloric dilator neurons in the stomatogastric nervous system of the lobster. The several-centimeters-long portions of these axons in the motor nerves depolarize in response to low concentrations of dopamine (DA) and exhibit peripheral spike initiation in the absence of centrally generated activity.

Collagen VI Regulates Motor Circuit Plasticity and Motor Performance by Cannabinoid Modulation [PDF]
The Journal of Neuroscience, 2021 Collagen VI is a key component of muscle basement membranes, and genetic variants can cause monogenic muscular dystrophies. Conversely, human genetic studies recently implicated collagen VI in central nervous system function, with variants causing the movement disorder dystonia.

THE NEURAL ORIGIN OF MUSCLE SYNERGIES
Frontiers in Computational Neuroscience, 2013 Muscle synergies are neural coordinative structures that function to alleviate the computational burden associated with the control of movement and posture. In this commentary, we address two critical questions: the explicit encoding of muscle synergies

Novel methods to enhance precision and reliability in muscle synergy identification during walking
Frontiers in Human Neuroscience, 2016 Muscle synergies are hypothesized to reflect modular control of muscle groups via descending commands sent through multiple neural pathways. Recently, the number of synergies has been reported as a functionally relevant indicator of motor control ...

Sensorimotor Self-organization via Circular-Reactions
Frontiers in Neurorobotics, 2021 Newborns demonstrate innate abilities in coordinating their sensory and motor systems through reflexes. One notable characteristic is circular reactions consisting of self-generated motor actions that lead to correlated sensory and motor activities. This

Dopaminergic Modulation of Motor Maps in Rat Motor Cortex: An In Vivo Study [PDF]
Neuroscience, 2009 While the primary motor cortex (M1) is know to receive dopaminergic projections, the functional role of these projections is poorly characterized. Here, it is hypothesized that dopaminergic signals modulate M1 excitability and somatotopy, two features of the M1 network relevant for movement execution and learning.

A Robotic Brain Scheme: Proposal Originated by a Modular Robotic Control
Applied Bionics and Biomechanics, 2007 A robot brain scheme has been implemented, based on and controlled by analog circuits and micro-controllers. The modules have been classified as: (a) world signal processing, (b) world signal relevance assessing, (c) pre-motor decisions, (d) motor ...

Psychosocial Modulators of Motor Learning in Parkinson’s Disease [PDF]
Frontiers in Human Neuroscience, 2016 Using the remarkable overlap between brain circuits affected in Parkinson's disease (PD) and those underlying motor sequence learning, we may improve the effectiveness of motor rehabilitation interventions by identifying motor learning facilitators in PD.

Effects of perturbations to balance on neuromechanics of fast changes in direction during locomotion. [PDF]
PLoS ONE, 2013 This study investigated whether the modular control of changes in direction while running is influenced by perturbations to balance. Twenty-two healthy men performed 90° side-step unperturbed cutting manoeuvres while running (UPT) as well as manoeuvres ...
