Dynamic encoding of movement direction in motor cortical neurons.

2 Nov 2009 When we perform a skilled movement such as reaching for an object, we can make use of prior information, for example about the location of the object in space. This helps us to prepare the movement, and we gain improved accuracy and speed during ...

Functional clustering of neurons in motor cortex determined by cellular resolution imaging in awake behaving mice.

2 Nov 2009 Macroscopic (millimeter scale) functional clustering is a hallmark characteristic of motor cortex spatial organization in awake behaving mammals; however, almost no information is known about the functional micro-organization (approximately 100 ...

The differential role of motor cortex in stretch reflex modulation induced by changes in environmental mechanics and verbal instruction.

19 Oct 2009 The motor cortex assumes an increasingly important role in higher mammals relative to that in lower mammals. This is true to such an extent that the human motor cortex is deeply involved in reflex regulation and it is common to speak of ...

Increased expression of the growth-associated protein 43 gene in the sensorimotor cortex of the macaque monkey after lesioning the lateral corticospinal tract.

18 Oct 2009 To investigate the neural basis for functional recovery of the cerebral cortex following spinal cord injury, we measured the expression of growth-associated protein 43 (GAP-43), which is involved in the process of synaptic sprouting. We determined ...

Cortical representation of ipsilateral arm movements in monkey and man.

12 Oct 2009 A fundamental organizational principle of the primate motor system is cortical control of contralateral limb movements. Motor areas also appear to play a role in the control of ipsilateral limb movements. Several studies in monkeys have shown that ...

Disruption of functional connectivity in clinically normal older adults harboring amyloid burden.

5 Oct 2009 Amyloid deposition is present in 20-50% of nondemented older adults yet the functional consequences remain unclear. The current study found that amyloid accumulation is correlated with functional disruption of the default network as measured by ...

Intracranial EEG reveals a time- and frequency-specific role for the right inferior frontal gyrus and primary motor cortex in stopping initiated responses.

5 Oct 2009 Inappropriate response tendencies may be stopped via a specific fronto/basal ganglia/primary motor cortical network. We sought to characterize the functional role of two regions in this putative stopping network, the right inferior frontal gyrus ...

Long-term modifications in motor cortical dynamics induced by intensive practice.

5 Oct 2009 The planning of goal-directed movements requires sensory, temporal, and contextual information to be combined. Sensorimotor functions are embedded in large neuronal networks, but it is unclear how networks organize their activity in space and time ...

Synaptic circuit abnormalities of motor-frontal layer 2/3 pyramidal neurons in an RNA interference model of methyl-CpG-binding protein 2 deficiency.

5 Oct 2009 Rett syndrome, an autism spectrum disorder with prominent motor and cognitive features, results from mutations in the gene for methyl-CpG-binding protein 2 (MeCP2). Here, to identify cortical circuit abnormalities that are specifically associated ...

The graphemic/motor frontal area Exner's area revisited.

29 Sep 2009 OBJECTIVE: In 1881, Exner first described a "graphic motor image center" in the middle frontal gyrus. Current psycholinguistic models of handwriting involve the conversion of abstract, orthographic representations into motor representations before a ...
