We have previously shown bilateral activation of motor pathways and the recruitment of additional motor areas in studies of groups of patients with recovery from motor stroke. We have now deveoloped a new positron emission tomographic technique to measure the changes in regional cerebral blood flow elicated duringsd a motor task in individual patients, relative to the cerebral activatuion found in normal subjects. The patterns of cerebral activation in each of 8 individual patients with… Expand
Cerebellar hemispheric activation ipsilateral to the paretic hand correlates with functional recovery after stroke.
TLDR
Functional MRI results support a role for the cerebellum in mediating functional recovery from stroke and suggest a possible link between cerebellar activation and behavioural recovery from hand weakness from stroke. Expand
Multimodal imaging of brain reorganization in motor areas of the contralesional hemisphere of well recovered patients after capsular stroke.
TLDR
Effective recovery is based on enhanced utilization of ipsi- and contralesional resources, basic corticospinal commands arise from the lesioned hemisphere without recruitment of ('latent') uncrossed corticOSPinal tract fibres and increased contralsional activity probably facilitates control of recovered motor function by operating at a higher-order processing level, similar to but not identical with the extended network concerned with complex movements in healthy subjects. Expand
Physiological studies of the corticomotor projection to the hand after subcortical stroke
TLDR
The findings indicate that there is functional reorganization of the corticomotor projection in subjects who regain a degree of motor control following a subcortical lesion sparing the motor cortex. Expand
Pilot study of functional MRI to assess cerebral activation of motor function after poststroke hemiparesis.
TLDR
The explanation offered for the findings is that preexisting uncrossed motor neural pathways may be accessed or recruited to compensate for damage to the crossed motor pathways after ischemic stroke. Expand
Contralesional Motor Cortex Activation Depends on Ipsilesional Corticospinal Tract Integrity in Well-Recovered Subcortical Stroke Patients
TLDR
There may be beneficial reorganization in contralesional secondary motor areas with increasing damage to the corticospinal tract after subcortical stroke with implications for motor recovery processes. Expand
Reorganization of the human ipsilesional premotor cortex after stroke.
TLDR
Results indicate that PMdAH participates as a substrate mediating functional recovery of executive motor function in patients with focal lesions of corticospinal outflow originating in M1 and good motor recovery, consistent with the hypothesis that the dorsal premotor cortex of the affected hemisphere can reorganize to control basic parameters of movement usually assigned to M1 function. Expand
Reorganization of sensory and motor systems in hemiplegic stroke patients. A positron emission tomography study.
TLDR
Passive movements in hemiplegic stroke patients before clinical recovery elicit some of the brain activation patterns that have been described during active movements after substantial motor recovery. Expand
Pattern of cortical reorganization in amyotrophic lateral sclerosis: a functional magnetic resonance imaging study
TLDR
The results demonstrate a general pattern of functional changes after motor neuron degeneration and support the concept of a structurally parallel and functionally specialized organization of voluntary motor control. Expand
Cortical motor and somatosensory representation: effect of cerebral lesions.
TLDR
Central lesions are more frequently associated with altered patterns in activation than lesions in noncentral locations, and the absence of activation in gyri adjacent to the sensorimotor strip has clinical significance for the planning of resections in the central area. Expand
The role of ipsilateral premotor cortex in hand movement after stroke
TLDR
Slowing of reaction time after premotor cortex TMS in the patients correlated inversely with the relative hemispheric lateralization of functional magnetic resonance imaging activation in PMd, suggesting that the increased activation in ipsilateral cortical motor areas during movements of a paretic hand represents a functionally relevant, adaptive response to the associated brain injury.

Functional reorganization of the brain in recovery from striatocapsular infarction in man
TLDR
It is shown that bilateral activation of motor pathways and the recruitment of additional sensorimotor areas and of other specific cortical areas are associated with recovery from motor stroke due to striatocapsular infarction. Expand

TLDR
The results suggest that ipsilateral motor pathways may play a role in the recovery of motor function after ischemic stroke. Expand
Supplementary motor area and other cortical areas in organization of voluntary movements in man.
TLDR
It is suggested that the supplementary motor areas are programming areas for motor subroutines and that these areas form a queue of time-ordered motor commands before voluntary movement are executed by way of the primary motor area. Expand
Motor responses after transcranial electrical stimulation of cerebral hemispheres with a degenerated pyramidal tract
TLDR
Motor responses were evoked in the thenar muscles by transcranial electrical cortex stimulation in 5 stroke patients with an isolated lacuna in the internal capsule, in whom wallerian degeneration of the pyramidal tract was demonstrated in vivo and polysynaptic corticoreticulospinal connections are suggested. Expand
Regional cerebral blood flow during voluntary arm and hand movements in human subjects.
TLDR
The data indicate that neither "fractionation" nor distal movement per se cause selective activation of sensorimotor cortex, and this finding does not prove unequivocally a "selective" role of the nonprimary motor areas in proximal movement. Expand
The role of cerebral cortex in the generation of voluntary saccades: a positron emission tomographic study.
TLDR
The frontal eye fields were discrete cortical regions consistently active during the generation of voluntary SEMs and uninfluenced by target presence, type of cue, or task complexity, indicating a predominantly motor function. Expand
Reshaping the cortical motor map by unmasking latent intracortical connections
TLDR
During pharmacological blockade of cortical inhibition in one part of the MI representation, movements of neighboring representations were evoked by stimulation in adjacent MI areas, suggesting that intracortical connections form a substrate for reorganization of cortical maps and that inhibitory circuits are critically placed to maintain or readjust the form of cortical motor representations.

The position and organization of motor fibers in the internal capsule found during stereotactic surgery.
TLDR
The results obtained indicate that pyramidal fibers are organized into a rostral-caudal face-arm-leg sequence and occupy a short compact band in the caudal third of the posterior limb of the internal capsule. Expand

Tracing of Neuronal Connections in the Human Brain by Magnetic Resonance Imaging in vivo
TLDR
In two patients with pure motor strokes due to small ischaemic lesions restricted to the internal capsule, magnetic resonance imaging disclosed a narrow band of pathological signal increase descending band‐like into the brain stem and ascending to the precentral gyrus, which corresponded to the well‐known path of the pyramidal tract.
