Primary motor cortex disinhibition during motor skill learning

Journal of Neurophysiology, 2014
Motor learning requires practice over a period of time and depends on brain plasticity, yet even for relatively simple movements, there are multiple practice strategies that can be used for skill acquisition. We investigated the role of intracortical inhibition in the primary motor cortex (M1) during motor skill learning.

Ipsilateral involvement of primary motor cortex during motor imagery

European Journal of Neuroscience, 2000
AbstractTo investigate whether motor imagery involves ipsilateral cortical regions, we studied haemodynamic changes in portions of the motor cortex of 14 right‐handed volunteers during actual motor performance (MP) and kinesthetic motor imagery (MI) of simple sequences of unilateral left or right finger movements, using functional magnetic resonance ...

Constraints on Somatotopic Organization in the Primary Motor Cortex

Journal of Neurophysiology, 2001
Since the 1870s, the primary motor cortex (M1) has been known to have a somatotopic organization, with different regions of cortex participating in control of face, arm, and leg movements. Through the middle of the 20th century, it seemed possible that the principle of somatotopic organization extended to the detailed representation of different body ...

Cortical Reorganization of Hand Motor Function to Primary Sensory Cortex in Hemiparetic Patients With a Primary Motor Cortex Infarct

Archives of Physical Medicine and Rehabilitation, 2005
To show cortical reorganization in hemiparetic patients with a primary motor cortex (M1) infarct including the precentral knob by using functional magnetic resonance imaging (fMRI).Case-control.Outpatient clinics in the rehabilitation department of a university hospital.Two stroke patients and 20 control subjects.By using fMRI, we evaluated the hand ...

Plasticity in the Motor Network Following Primary Motor Cortex Lesion

2013
The behavioral deficits following stroke are particularly evident in the fine control of force, movement, and posture of the arm and hand. However, functional recovery continues in the weeks and months after the initial lesion. Various animal models of stroke have been used to investigate the mechanisms involved with this recovery.
