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.

Comparison of cerebral activation between motor execution and motor imagery of self-feeding activity [PDF]
Neural Regeneration Research, 2021 Motor imagery is defined as an act wherein an individual contemplates a mental action of motor execution without apparent action. Mental practice executed by repetitive motor imagery can improve motor performance without simultaneous sensory input or ...

Corticothalamic neurons in motor cortex have a permissive role in motor execution [PDF]
Nature Communications, 2022 The primary motor cortex (M1) is a central hub for motor learning and execution. M1 is composed of heterogeneous cell types with varying relationships to movement.

Social Motor Priming: when offline interference facilitates motor execution [PDF]
PeerJ, 2019 Many daily activities involve synchronizing with other people’s actions. Previous literature has revealed that a slowdown of performance occurs whenever the action to be carried out is different to the one observed (i.e., visuomotor interference ...

Disrupted topological organization of the motor execution network in Wilson's disease [PDF]
Frontiers in Neurology, 2022 ObjectiveThere are a number of symptoms associated with Wilson's disease (WD), including motor function damage. The neuropathological mechanisms underlying motor impairments in WD are, however, little understood. In this study, we explored changes in the

Motor Planning, Not Execution, Separates Motor Memories [PDF]
Neuron, 2016 Recent theories of limb control emphasize motor cortex as a dynamical system, with planning setting the initial neural state, and execution arising from the self-limiting evolution of the intrinsic neural dynamics.

Brain Function and Upper Limb Deficit in Stroke With Motor Execution and Imagery: A Cross-Sectional Functional Magnetic Resonance Imaging Study [PDF]
Frontiers in Neuroscience, 2022 BackgroundMotor imagery training might be helpful in stroke rehabilitation. This study explored if a specific modulation of movement-related regions is related to motor imagery (MI) ability.MethodsTwenty-three patients with subcortical stroke and 21 age ...

Changes in network connectivity during motor imagery and execution. [PDF]
PLoS ONE, 2018 Recent studies of functional or effective connectivity in the brain have reported that motor-related brain regions were activated during motor execution and motor imagery, but the relationship between motor and cognitive areas has not yet been completely

Engaging distributed cortical and cerebellar networks through motor execution, observation, and imagery [PDF]
Frontiers in Systems Neuroscience, 2023 When we interact with the environment around us, we are sometimes active participants, making directed physical motor movements and other times only mentally engaging with our environment, taking in sensory information and internally planning our next ...

Motor imagery and action execution [PDF]
Ergo, an Open Access Journal of Philosophy, 2020 What triggers the execution of actions? What happens in that moment when an action is triggered? What mental state is there at the moment of action-execution that was not there a second before?
