Acute aerobic exercise modulates primary motor cortex inhibition

Experimental Brain Research, 2016
Aerobic exercise can enhance neuroplasticity although presently the neural mechanisms underpinning these benefits remain unclear. One possible mechanism is through effects on primary motor cortex (M1) function via down-regulation of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA).

Theta‐burst stimulation over primary motor cortex degrades early motor learning

European Journal of Neuroscience, 2010
AbstractTheta‐burst stimulation (TBS) is currently used for inducing long‐lasting changes in primary motor cortex (M1) excitability. More information is needed on how M1 is involved in early motor learning (practice‐related improvement in motor performance, motor retention and motor consolidation).

Arterial vascularization of primary motor cortex (precentral gyrus)

Surgical Neurology, 2005
The precentral gyrus (PG) is the primary motor area and is one of the most eloquent brain regions of neurosurgical interest. Although the arterial supply to the PG is generally known, contributions from different arterial branches such as the anterior cerebral artery (ACA), posterior cerebral artery (PCA), and middle cerebral artery (MCA) have not been

Primary motor cortex is involved in bimanual coordination

Nature, 1998
Many voluntary movements involve coordination between the limbs. However, there have been very few attempts to study the neuronal mechanisms that mediate this coordination. Here we have studied the activity of cortical neurons while monkeys performed tasks that required coordination between the two arms.

Primary writing tremor: motor cortex reorganisation and disinhibition

Journal of Clinical Neuroscience, 2005
Primary writing tremor (PWT) is a task-specific tremor of uncertain origin. There has been debate as to whether PWT represents a variant of essential tremor or a tremulous form of focal dystonia related to writer's cramp. In writer's cramp there is evidence of changes in intracortical inhibition (ICI), as well as cortical motor reorganisation.To study ...

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.

New Views of the Primary Motor Cortex

The Neuroscientist, 2000
For 100 years, from the 1870s to the 1970s, somatotopic organization was considered the hallmark of the primary motor cortex (M1). M1 neurons were viewed as upper motor neurons, implying that their organization and function were upstream versions of the spinal motoneurons to which they project.
