PURPOSE OF REVIEW: The present article describes current indications for functional MRI in the preoperative planning of neurosurgical patients. Functional MRI continues to have an expanding role. RECENT FINDINGS: There are three main categories of patients who commonly undergo preoperative functional MRI. Patients with lesions close to eloquent cortex can benefit from preoperative functional MRI to assess resectability and reduce the possibility of functional deficit. The second group are those patients who have functional MRI as part of their preoperative planning to localize language dominance and for functional localization of memory. The final group are those patients in whom attempts are made to image and localize abnormal brain function. This has a specific application in the field of epilepsy surgery (electroencephalographic-correlated functional MRI). These three roles require different spatial resolutions. Advances in multimodality imaging are enabling more accurate localization of function intraoperatively. SUMMARY: It is hoped that the increasing use of functional MRI in combination with both preoperative and intraoperative imaging modalities may reduce the risk of neurological deficit while improving completeness of resection. Electroencephalographic-correlated functional MRI may provide an additional method for localization of epileptogenic foci. 相似文献

ObjectiveThe aim of the present study was to compare localization of the language cortex using electrical cortical stimulation (ECS) and functional magnetic resonance imaging (fMRI) to establish the relevance of fMRI language mapping.MethodsLanguage mapping with fMRI and functional ECS mapping were retrospectively compared in ten patients with refractory epilepsy who underwent fMRI language mapping and functional ECS mapping between June 2012 and April 2019. A shiritori task, a popular Japanese word chain game, was used for fMRI language mapping.ResultsBOLD signal activation was observed in the left inferior frontal gyrus (including the pars opecularis and the pars triangularis), and superior temporal gyrus, which is a language-related area, as well as in the left superior and middle frontal gyri, the intraparietal sulcus, and fusiform gyrus. These results were compared with ECS to elucidate the functional role of the activated areas during fMRI language tasks. These activated areas included language areas, negative motor areas, supplementary motor areas (SMAs), and non-functional areas.ConclusionThe activated areas of fMRI language mapping include language-related areas, the negative motor area, and SMAs. These findings suggest the involvement of language and higher order motor networks in verbal expression. 相似文献

ABSTRACT: Functional recovery is an important treatment target in schizophrenia. Although medication is effective at reducing positive symptoms of the disorder, these improvements do not translate to improved functioning. In this study, schizophrenia outpatients (N = 54) received the psychosocial treatment Functional Adaptation Skills Training. Hierarchical regression analyses determined whether baseline neurocognitive, symptom, course of illness, and demographic variables predicted improvement in performance-based measures of functional competence and case manager-rated real-world behavior after the intervention. Consistent with previous research, neurocognition emerged as a predictor of improved competence and behavior. Symptoms played a minor role in predicting change; however, institutionalization history seemed to be an important rate limiter for functional recovery. Correlations among change scores were modest, with evidence for concomitant changes in competence and performance. The predictors of change after psychosocial treatment vary by the domain (e.g., adaptive and interpersonal) of functioning and the level of assessment (e.g., competence and performance). 相似文献

The aberrant static functional connectivity of brain network has been widely investigated in patients with functional constipation (FCon). However, the dynamics of brain functional connectivity in FCon patients remained unknown. This study aimed to detect the brain dynamics of functional connectivity states and network topological organizations of FCon patients and investigate the correlations of the aberrant brain dynamics with symptom severity. Eighty‐three FCon patients and 80 healthy subjects (HS) were included in data analysis. The spatial group independent component analysis, sliding‐window approach, k‐means clustering, and graph‐theoretic analysis were applied to investigate the dynamic temporal properties and coupling patterns of functional connectivity states, as well as the time‐variation of network topological organizations in FCon patients. Four reoccurring functional connectivity states were identified in k‐means clustering analysis. Compared to HS, FCon patients manifested the lower occurrence rate and mean dwell time in the state with a complex connection between default mode network and cognitive control network, as well as the aberrant anterior insula–cortical coupling patterns in this state, which were significantly correlated with the symptom severity. The graph‐theoretic analysis demonstrated that FCon patients had higher sample entropy at the nodal efficiency of anterior insula than HS. The current findings provided dynamic perspectives for understanding the brain connectome of FCon and laid the foundation for the potential treatment of FCon based on brain connectomics. 相似文献

Objective To describe the technique of transsylvian–transventricular functional hemispherectomy developed at our institution.Methods We review appropriate patient selection and evaluation, timing of surgery, selection of surgical approach, preoperative preparation, details of operative procedure, and postoperative management.Conclusions The transsylvian “keyhole” functional hemispherectomy technique involves a smaller craniotomy than other functional hemispherectomy techniques and consists of transsylvian exposure, resection of mesial temporal structures, transventricular frontobasal disconnection, callosotomy, and occipitoparietal disconnection. The key advantages of this approach compared to the Rasmussen’s “classic” functional hemispherectomy are smaller exposure, shorter operative time, and lower blood loss. The efficacy of functional hemispherectomy procedures in achieving seizure freedom appears to be at least as good compared to resective procedures. The long-term complication rate will require longer follow-up times. 相似文献

In this work, we focus on explicitly nonlinear relationships in functional networks. We introduce a technique using normalized mutual information (NMI) that calculates the nonlinear relationship between different brain regions. We demonstrate our proposed approach using simulated data and then apply it to a dataset previously studied by Damaraju et al. This resting‐state fMRI data included 151 schizophrenia patients and 163 age‐ and gender‐matched healthy controls. We first decomposed these data using group independent component analysis (ICA) and yielded 47 functionally relevant intrinsic connectivity networks. Our analysis showed a modularized nonlinear relationship among brain functional networks that was particularly noticeable in the sensory and visual cortex. Interestingly, the modularity appears both meaningful and distinct from that revealed by the linear approach. Group analysis identified significant differences in explicitly nonlinear functional network connectivity (FNC) between schizophrenia patients and healthy controls, particularly in the visual cortex, with controls showing more nonlinearity (i.e., higher normalized mutual information between time courses with linear relationships removed) in most cases. Certain domains, including subcortical and auditory, showed relatively less nonlinear FNC (i.e., lower normalized mutual information), whereas links between the visual and other domains showed evidence of substantial nonlinear and modular properties. Overall, these results suggest that quantifying nonlinear dependencies of functional connectivity may provide a complementary and potentially important tool for studying brain function by exposing relevant variation that is typically ignored. Beyond this, we propose a method that captures both linear and nonlinear effects in a “boosted” approach. This method increases the sensitivity to group differences compared to the standard linear approach, at the cost of being unable to separate linear and nonlinear effects. 相似文献
