..The authors reasoned that early methods may have been insensitive to such dysfunction, which may now be detectable with improved technology...

..Recent studies suggest that positron emission tomography may be a reliable predictive indicator of clinical outcome following surgical treatment for epilepsy...

..Dexetimide is a specific mAChR antagonist that has been labeled recently with 76Br. This first study in humans focused on regional distribution and binding kinetics of [76Br]4-bromodexetimide (BDEX) in patients with MTLE...

..Such functional asymmetry in temporal processing is likely to contribute to language lateralization from the lowest levels of cortical processing...

..These data suggest that the 3D anatomy of the cerebral cortex may facilitate sulcal recognition, and sulcal subdivision into smaller morphological elements, bearing remarkable relationships with functional cortical maps...

..These findings help to understand the limit of deafness rehabilitation in the time domain and should be taken into account in future devices development...

..Therefore, the convergent anatomical and functional temporal abnormalities observed in autism may be important in the understanding of brain behavior relationships in this severe developmental disorder...

..We know remarkably little about the mechanisms underlying cortical activation. Such mechanisms might be better understood by studying the effect of well-localized lesions on the cortical activations in simple paradigms...

..Results are also discussed in terms of the specific kinds of OKN-related information processing subserved by each area in this network...

..This may be explained by the limited duration of hypoglycaemic coma induced by conventional insulin treatment...

..Such localized abnormalities were not detected with the low resolution PET camera,. This study suggests that high resolution PET camera combined with statistical parametric mapping is useful to understand developmental disorders...

..This can be accomplished using adequate modifications of the reconstruction parameters. Such modifications can be used to help in the longitudinal monitoring of parkinsonian patients using different tomographs...

..However, the benefit of SAH in terms of functional outcome is debated. In this study, we aimed to assess the metabolic consequences of SAH...

..From a clinical perspective, this study provides new information on the impact of left SFG lesions on cognition that will be of use to neurologists and neurosurgeons...

..These findings suggest that a reduction of temporal pole neocortical grey matter might contribute to temporal pole hypometabolism in temporal lobe epilepsy...

..A direct application would be the improvement of cognitive and/or behavioural rehabilitation of patients with brain damage...

..This paper reviews recent evidence provided by studies in healthy individuals and patients with Parkinson's disease or schizophrenia supporting the role of dopamine in normal and pathological cognitive processes...

..MRI is the gold standard to investigate CNS lesions of ND-LCH but little is known about functional changes observed in this disease...

..To test this hypothesis, we studied the activation of human temporal voice areas (TVA) using a well-standardized PET paradigm adapted from previous functional MRI (fMRI) studies...

..The method complements the functional imaging techniques, as it tells which regions are necessary for a given function and it explores cortical regions as well as the white matter...

..The aim of the study was to evaluate whether leukoaraiosis (LA) is a risk factor for symptomatic intracerebral hemorrhage (sICH) in patients treated with thrombolysis for acute stroke...

..This review is part of the INMED/TINS special issue "Nature and nurture in brain development and neurological disorders", based on presentations at the annual INMED/TINS symposium (http://inmednet.com/)...

..Preliminary data, which suggest that the speed and quality of glycemic control may be decisive in the efficacy of treatment, merit testing in a randomized trial...

..Hypometabolism located in the insula did not influence postoperative outcome after anterior lobectomy...

..These results suggest that the prodigious capacities may be sustained by memory processing...

..The abnormal cortical auditory processing observed in both children and adults with autism could be involved in inadequate behavioral responses to sounds and in language impairments characteristic of autism...

..CONCLUSIONS: These findings suggest that abnormal auditory cortical processing is implicated in the language impairments and the inadequate response to sounds typically seen in autism...

..These findings suggest abnormal cortical processing of socially relevant auditory information in autism...

..The more severe the autistic syndrome, the more rCBF is low in this region, suggesting that left superior temporal hypoperfusion is related to autistic behavior severity...
