Brain network and activity in frontal regions change in the process of visuomotor adaptation [PDF]

Scientific Reports
Frontal regions are involved in early stages of motor adaptation. However, the interactions between prefrontal cortex (PFC) and motor cortex (MC) remain unclear.

Study on the variable side - deep fertilization control system for rice based on soil electrical conductivity [PDF]

Frontiers in Plant Science
To address the problem that current rice fertilization devices rely on experience-based settings of fertilizer application rates and are unable to dynamically adjust according to soil fertility, resulting in low fertilizer use efficiency, a rice side ...

Enhanced Information Flow From Cerebellum to Secondary Visual Cortices Leads to Better Surgery Outcome in Degenerative Cervical Myelopathy Patients: A Stochastic Dynamic Causal Modeling Study With Functional Magnetic Resonance Imaging

Frontiers in Human Neuroscience, 2021
Degenerative cervical myelopathy (DCM) damages the spinal cord, resulting in long-term neurological impairment including motor and visual deficits. Given that visual feedback is crucial in guiding movements, the visual disorder may be a cause of motor ...

Altered Pallidocortical Low-Beta Oscillations During Self-Initiated Movements in Parkinson Disease

Frontiers in Systems Neuroscience, 2020
BackgroundParkinson disease (PD) patients have difficulty with self-initiated (SI) movements, presumably related to basal ganglia thalamocortical (BGTC) circuit dysfunction, while showing less impairment with externally cued (EC) movements.ObjectivesWe ...

Design and Analysis of Interior Permanent Magnet Motor With Magnetic Isolation and Heat Dissipation Integrated Auxiliary Slot

IEEE Access, 2023
This paper presents a novel auxiliary slot interior permanent-magnet (IPM) motor. It not only plays the role of magnetic isolation and reduces the eddy-current (EC) loss, but also facilitates the ventilation and heat dissipation of the rotor.

Eyes-Open and Eyes-Closed Resting State Network Connectivity Differences

Brain Sciences, 2023
Resting state networks comprise several brain regions that exhibit complex patterns of interaction. Switching from eyes closed (EC) to eyes open (EO) during the resting state modifies these patterns of connectivity, but precisely how these change remains

Aging interferes central control mechanism for eccentric muscle contraction

Frontiers in Aging Neuroscience, 2014
Previous studies report greater activation in the cortical motor network in controlling eccentric contraction (EC) than concentric contraction (CC) despite lower muscle activation level associated with EC vs. CC in healthy, young individuals.
