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

Neural 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 ...

Inhibition of the primary motor cortex and the upgoing thumb sign

eNeurologicalSci, 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.

Cellular anatomy of the mouse primary motor cortex [PDF]

Nature, 2021
AbstractAn essential step toward understanding brain function is to establish a structural framework with cellular resolution on which multi-scale datasets spanning molecules, cells, circuits and systems can be integrated and interpreted1. Here, as part of the collaborative Brain Initiative Cell Census Network (BICCN), we derive a comprehensive cell ...

Dopaminergic signals in primary motor cortex [PDF]

International 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).

Consolidation of Dynamic Motor Learning Is Not Disrupted by rTMS of Primary Motor Cortex [PDF]

Current Biology, 2004
Motor skills, once learned, are often retained over a long period of time. However, such learning first undergoes a period of consolidation after practice. During this time, the motor memory is susceptible to being disrupted by the performance of another motor-learning task. Recently, it was shown that repetitive transcranial magnetic stimulation (rTMS)

Movement Decomposition in the Primary Motor Cortex [PDF]

Cerebral 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 Primary Motor Cortex: The Hub of Motor Learning in Rodents

Neuroscience, 2022
The primary motor cortex, a dynamic center for overall motion control and decision making, undergoes significant alterations upon neural stimulation. Over the last few decades, data from numerous studies using rodent models have improved our understanding of the morphological and functional plasticity of the primary motor cortex.

Contribution of primary motor cortex to compensatory balance reactions [PDF]

BMC Neuroscience, 2012
Rapid compensatory arm reactions represent important response strategies following an unexpected loss of balance. While it has been assumed that early corrective actions arise largely from sub-cortical networks, recent findings have prompted speculation about the potential role of cortical involvement.

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

Brain 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 transcranial magnetic stimulation (TMS), in a laser-paired associative stimulation design (Laser-PAS)

Changes in excitability and GABAergic neuronal activity of the primary somatosensory cortex after motor learning

Frontiers in Neuroscience, 2022
IntroductionIt is widely known that motor learning changes the excitability of the primary motor cortex. More recently, it has been shown that the primary somatosensory cortex (S1) also plays an important role in motor learning, but the details have not ...
