We measured the distribution of regional cerebral blood flow with positron emission tomography while three subjects moved their hand, shoulder, or leg. The images were coregistered with each individual's anatomic magnetic resonance scans. The data were analyzed for each individual to avoid intersubject averaging and so to preserve individual gyral anatomy. Instead of inspecting all pixels, we prospectively restricted the data analysis to particular areas of interest. These were defined on basis…

Segregation of somatosensory activation in the human rolandic cortex using fMRI.

Functional magnetic resonance imaging evidence is provided for the functional delineation of somatosensory representations in the human central sulcus region and strong evidence for the existence of a distinct representation within area 3a in humans is provided.

Optimized activation of the primary sensorimotor cortex for clinical functional MR imaging.

A simple functional MR imaging paradigm for selective activation of the primary sensorimotor cortex was designed and it was revealed that the highly selective primary motor activation was due to it being restricted to contralateral finger movements, as opposed to the nonprimary motor areas, which were activated by ipsilateral,contralateral, and bilateral finger movements alike.

The question whether a motor task engages only the "motor domain" of the supplementary motor/premotor cortex or in addition the "cognitive domain of the prefrontal cortex can only be answered by superimposing the functional activation map with the microstructural population map of area 6.

Motor areas of the frontal cortex in patients with motor eloquent brain lesions.

The distribution of primary and polysynaptic motor areas changes in patients with brain tumors and highly depends on tumor location, so these data should be considered for resection planning.

A PET Study of Visuomotor Learning under Optical Rotation

Results reveal that sensorimotor learning accompanies changes in the recruited cortical areas during different stages of the adaptation, reflecting the different functional roles of each area for different components of adaptation, from learning of new sensorsimotor coordination to retention or retrieval of acquired coordination.

Sensorimotor cortex localization: comparison of magnetoencephalography, functional MR imaging, and intraoperative cortical mapping.

Although both MEG and functional MR imaging can provide useful information for neurosurgical planning, in the present study, MEG proved to be superior for locating the central sulcus.

Activation of the dorsal premotor cortex and pre-supplementary motor area of humans during an auditory conditional motor task.

The results suggest that the PMd along with the pre-SMA are the sites where more general and extensive sensorimotor integration takes place in human cerebral cortex.



Somatotopic mapping of the primary motor cortex in humans: activation studies with cerebral blood flow and positron emission tomography.

The somatotopic representation of the human primary motor cortex was examined noninvasively with estimates of cerebral blood flow obtained with positron emission tomography and it was determined that two foci of activation in theprimary motor cortex could be discriminated with a 95% confidence if they were separated by 5.4 mm.

Functional anatomy of the mental representation of upper extremity movements in healthy subjects.

Investigating differences in the distribution of relative regional cerebral blood flow during motor imagery and execution of a joy-stick movement with positron emission tomography suggested that imagined movements can be viewed as a special form of "motor behavior' that activate areas associated heretofore with selection of actions and multisensory integration.

Functional anatomy of reaching and visuomotor learning: a positron emission tomography study.

The results indicate that there are at least two different types of functional fields in the posterior part of the superior parietal lobule; one is active during reaching for the targets when guided by internal representations of target positions; the other likely represents the storage sites of visual target information that is addressed in long-term memory.

Area V5 of the human brain: evidence from a combined study using positron emission tomography and magnetic resonance imaging.

P positron emission tomography was used to determine the foci of relative cerebral blood flow increases produced when subjects viewed a moving checkerboard pattern, compared to viewing the same pattern when it was stationary.

Human cingulate and paracingulate sulci: pattern, variability, asymmetry, and probabilistic map.

The results revealed considerable variability in the location of some of the above morphological features and a striking hemispheric asymmetry in the prominence of the PCS.

Role of the human anterior cingulate cortex in the control of oculomotor, manual, and speech responses: a positron emission tomography study.

The localization of output-specific rCBF changes within the human ACC is consistent with the known somatotopic organization of the cingulate cortex in the monkey, and it is tentatively proposed that the ACC participates in motor control by facilitating the execution of the appropriate responses and/or suppressing the Execution of the inappropriate ones.

Functional reorganization of the brain in recovery from striatocapsular infarction in man

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.

Mapping of human and macaque sensorimotor areas by integrating architectonic, transmitter receptor, MRI and PET data.

Receptor findings provide new criteria for a more detailed mapping in the human brain which cannot be achieved by cytoarchitectonic analysis alone and are incorporated into a recently developed computerised brain atlas.

Motor areas of the medial wall: a review of their location and functional activation.

The analysis suggests that it is possible to identify at least four separate cortical areas on the medial wall of the hemisphere, which appear to be analogous to the pre-SMA, the SMA proper, and two of the cingulate motor areas of the monkey.

The functional anatomy of motor recovery after stroke in humans: A study with positron emission tomography

The results suggest that ipsilateral motor pathways may play a role in the recovery of motor function after ischemic stroke.
