New Insights into Motor Cortex [PDF]

open access: yesNeuron, 2011
An exciting new experiment on the motor cortex of monkeys, by Shenoy and colleagues, begins to elucidate how the neuronal ensemble travels in a systematic fashion through state space. This trajectory through state space may help to explain how the motor cortex sets up and then triggers arm movements.

Temporal properties of cerebellar-dependent memory consolidation [PDF]

open access: yes, 2004
Classical conditioning of the nictitating membrane response in rabbits is a well defined model of cerebellar-dependent motor memory. This memory undergoes a period of consolidation after the training session, when it is sensitive to reversible ...

Low-Intensity Transcranial Ultrasound Stimulation Modulates the Excitability of Motor Cortical Neural Activity by Stimulating the Cerebellum

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering
Functional connectivity between the cerebellum and the motor cortex is critical for motor function. Low-intensity transcranial ultrasound stimulation (TUS) has been proved to directly activate cerebellar neural activity.

Corticospinal Circuits from the Sensory and Motor Cortices Differentially Regulate Skilled Movements through Distinct Spinal Interneurons

open access: yesCell Reports, 2018
Summary: Little is known about the organizational and functional connectivity of the corticospinal (CS) circuits that are essential for voluntary movement.

A longitudinal study of hand motor recovery after sub-acute stroke: a study combined FMRI with diffusion tensor imaging. [PDF]

open access: yesPLoS ONE, 2013
Previous studies have shown that motor recovery of stroke can be assessed by the cortical activity and the structural integrity of the corticospinal tract (CST), but little is known about the relation between the cortical activity and the structural ...

Dynamic Increase in Corticomuscular Coherence during Bilateral, Cyclical Ankle Movements [PDF]

open access: yes, 2017
In humans, the midline primary motor cortex is active during walking. However, the exact role of such cortical participation is unknown. To delineate the role of the primary motor cortex in walking, we examined whether the primary motor cortex would ...

Isolated shoulder weakness as a result of a cortical infarction in the precentral gyrus [PDF]

open access: yesJournal of Community Hospital Internal Medicine Perspectives, 2015
Since its discovery, our understanding of the primary motor cortex has continued to evolve. The presentations of rare, isolated, motor palsies of small muscle groups have heavily contributed to the characterization of the somatotopic representation of ...

Suppressing Systemic Interference in fNIRS Monitoring of the Hemodynamic Cortical Response to Motor Execution and Imagery

open access: yesFrontiers in Human Neuroscience, 2018
Hemodynamic response to motor execution (ME) and motor imagery (MI) was investigated using functional near-infrared spectroscopy (fNIRS). We used a 31 channel fNIRS system which allows non-invasive monitoring of cerebral oxygenation changes induced by ...

Task-free functional MRI in cervical dystonia reveals multi-network changes that partially normalize with botulinum toxin. [PDF]

open access: yesPLoS ONE, 2013
Cervical dystonia is characterized by involuntary, abnormal movements and postures of the head and neck. Current views on its pathophysiology, such as faulty sensorimotor integration and impaired motor planning, are largely based on studies of focal hand

The Motor Cortex Communicates with the Kidney [PDF]

open access: yesThe Journal of Neuroscience, 2012
We used retrograde transneuronal transport of rabies virus from the rat kidney to identify the areas of the cerebral cortex that are potential sources of central commands for the neural regulation of this organ. Our results indicate that multiple motor and nonmotor areas of the cerebral cortex contain output neurons that indirectly influence kidney ...
