Pain-motor integration in the primary motor cortex in Parkinson's disease [PDF]

open access: yesBrain Stimulation, 2017
In Parkinson's disease (PD), the influence of chronic pain on motor features has never been investigated. We have recently designed a technique that combines nociceptive system activation by laser stimuli and primary motor cortex (M1) activation through ...

Plasticity of the Primary Motor Cortex in Patients with Primary Brain Tumors [PDF]

open access: yesNeural Plasticity, 2020
There are two neuron-level mechanisms proposed to underlie neural plasticity: recruiting neurons nearby to support the lost function (ipsilesional plasticity) and uncovering latent pathways that can assume the function that was lost (contralesional ...

Dopaminergic signals in primary motor cortex [PDF]

open access: yesInternational Journal of Developmental Neuroscience, 2009
AbstractBrainstem monoamine areas such as the ventral tegmental area (VTA) send dopaminergic projections to the cerebral cortex that are widely distributed across different cortical regions. Whereas the projection to prefrontal areas (PFC) has been studied in detail, little is known about dopaminergic projections to primary motor cortex (M1).

Movement Decomposition in the Primary Motor Cortex [PDF]

open access: yesCerebral Cortex, 2018
Abstract A complex action can be described as the composition of a set of elementary movements. While both kinematic and dynamic elements have been proposed to compose complex actions, the structure of movement decomposition and its neural representation remain unknown.

The role of the left primary motor cortex in apraxia. [PDF]

open access: yesNeurol Res Pract
Abstract Background Apraxia is a motor-cognitive disorder that primary sensorimotor deficits cannot solely explain. Previous research in stroke patients has focused on damage to the fronto-parietal praxis networks in the left hemisphere (LH) as the cause of apraxic deficits.

Inhibition of the primary motor cortex and the upgoing thumb sign

open access: yeseNeurologicalSci, 2017
Background: The upgoing thumb sign has been frequently observed in patients with minor strokes and transient ischemic attacks as an indicator of brain involvement.

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 ...

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 ...

Partially Overlapping Sensorimotor Networks Underlie Speech Praxis and Verbal Short-Term Memory: Evidence from Apraxia of Speech Following Acute Stroke

open access: yesFrontiers in Human Neuroscience, 2014
We tested the hypothesis that motor planning and programming of speech articulation and verbal short-term memory (vSTM) depend on partially overlapping networks of neural regions. We evaluated this proposal by testing 76 individuals with acute ischemic

Transcranial direct current stimulation to facilitate neurofunctional rehabilitation in children with autism spectrum disorder: a protocol for a randomized, sham-controlled, double-blind clinical trial

open access: yesFrontiers in Neurology, 2023
BackgroundAnodal transcranial direct current stimulation (tDCS) over the primary motor cortex and cerebellum is gaining prominence in the literature due to its potential to favor learning and motor performance. If administered during motor training, tDCS
