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 ...

A posture subspace in the primary motor cortex. [PDF]

open access: yesNeuron
To generate movements, the brain must combine information about movement goal and body posture. The motor cortex (primary motor cortex [M1]) is a key node for the convergence of these information streams. How are posture and goal signals organized within M1's activity to permit the flexible generation of movement commands?

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.

Robot-assisted image-guided transcranial magnetic stimulation for somatotopic mapping of the motor cortex: a clinical pilot study. [PDF]

open access: yes, 2009
Shape and exact location of motor cortical areas varies among individuals. The exact knowledge of these locations is crucial for planning of neurosurgical procedures.

Cellular anatomy of the mouse primary motor cortex [PDF]

open access: yesNature, 2021
Abstract An 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 interpreted 1 .

Attention-dependent modulation of neural activity in primary sensorimotor cortex [PDF]

open access: yes, 2013
Although motor tasks at most times do not require much attention, there are findings that attention can alter neuronal activity not only in higher motor areas but also within the primary sensorimotor cortex.

Cerebellum to motor cortex paired associative stimulation induces bidirectional STDP-like plasticity in human motor cortex [PDF]

open access: yes, 2012
The cerebellum is crucially important for motor control and adaptation. Recent non-invasive brain stimulation studies have indicated the possibility to alter the excitability of the cerebellum and its projections to the contralateral motor cortex, with ...

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 ...

Preconditioning of low-frequency repetitive transcranial magnetic stimulation with transcranial direct current stimulation: evidence for homeostatic plasticity in the human motor cortex [PDF]

open access: yes, 2004
Recent experimental work in animals has emphasized the importance of homeostatic plasticity as a means of stabilizing the properties of neuronal circuits. Here, we report a phenomenon that indicates a homeostatic pattern of cortical plasticity in healthy
