Aging Changes Effective Connectivity of Motor Networks During Motor Execution and Motor Imagery [PDF]
Frontiers in Aging Neuroscience, 2019 Age-related neurodegenerative and neurochemical changes are considered to be the basis for the decline of motor function; however, the change of effective connections in cortical motor networks that come with aging remains unclear.

Efficiency at maximum power of motor traffic on networks [PDF]
Physical Review E, 2014 We study motor traffic on Bethe networks subject to hard-core exclusion for both tightly coupled one-state machines and loosely coupled two-state machines that perform work against a constant load. In both cases we find an interaction-induced enhancement

Motor networks, but also non-motor networks predict motor signs in Parkinson’s disease
NeuroImage: Clinical, 2023 Investigate the brain functional networks associated with motor impairment in people with Parkinson's disease (PD).PD is primarily characterized by motor dysfunction. Resting-state functional connectivity (RsFC) offers a unique opportunity to non-invasively characterize brain function.

A dual larynx motor networks hypothesis [PDF]
Philosophical Transactions of the Royal Society B, 2021 Humans are vocal modulators par excellence. This ability is supported in part by the dual representation of the laryngeal muscles in the motor cortex. Movement, however, is not the product of motor cortex alone but of a broader motor network. This network consists of brain regions which contain somatotopic maps that parallel the organisation in motor ...

Precise motor rhythmicity relies on motor network responsivity
Cerebral Cortex, 2022 AbstractRhythmic movements are the building blocks of human behavior. However, given that rhythmic movements are achieved through complex interactions between neural modules, it remains difficult to clarify how the central nervous system controls motor rhythmicity. Here, using a novel tempo-precision trade-off paradigm, we first modeled interindividual

Fine motor skills and motor control networking in developmental age
American Journal of Human Biology, 2022 AbstractObjectivesWe investigated the relationships between fine motor skills, fitness, anthropometrics, gender and perceived motor performance in school beginners. The aim of our study was to delineate whether and to what extent fine motor control would show meaningful synchrony with other motor variables in the age of onset of handwriting in school ...

Translational Model of Cortical Premotor-Motor Networks [PDF]
Cerebral Cortex, 2021 Abstract Deciphering the physiological patterns of motor network connectivity is a prerequisite to elucidate aberrant oscillatory transformations and elaborate robust translational models of movement disorders. In the proposed translational approach, we studied the connectivity between premotor (PMC) and primary motor cortex (M1) by ...

Generation of Variants of a Motor Act in a Modular and Hierarchical Motor Network [PDF]
Current Biology, 2005 Most motor systems can generate a variety of behaviors, including categorically different behaviors and variants of a single motor act within the same behavioral category. Previous work indicated that many pattern-generating interneuronal networks may have a modular organization and that distinct categories of behaviors can be generated through ...

Mapping grip force to motor networks
NeuroImage, 2021 There is ongoing debate about the role of cortical and subcortical brain areas in force modulation. In a whole-brain approach, we sought to investigate the anatomical basis of grip force whilst acknowledging interindividual differences in connectivity patterns.

Synaptic Scaling and the Development of a Motor Network [PDF]
Journal of Neuroscience, 2010 Neurons respond homeostatically to chronic changes in network activity with compensatory changes such as a uniform alteration in the size of miniature postsynaptic current (mPSC) amplitudes termed synaptic scaling. However, little is known about the impact of synaptic scaling on the function of neural networks in vivo.
