Despite a better understanding of their anatomy, the functional role of frontal pathways, i.e., the fronto-striatal tract (FST) and frontal aslant tract (FAT), remains obscure. We studied 19 patients who underwent awake surgery for a frontal glioma (14 left, 5 right) by performing intraoperative electrical mapping of both fascicles during motor and language(More)
OBJECT Recently, intraoperative mapping has disclosed that, in addition to the classic language centers (that is, the Broca and Wernicke centers), other cortical regions may also play an important role in language organization. In the prefrontal cortex, although the lateral superior frontal gyrus (LSFG) could have language-related functions, there are no(More)
OBJECT Disturbance of the arcuate fasciculus in the dominant hemisphere is thought to be associated with language-processing disorders, including conduction aphasia. Although the arcuate fasciculus can be visualized in vivo with diffusion tensor imaging (DTI) tractography, its involvement in functional processes associated with language has not been shown(More)
Recently, delivery technologies of visual and auditory information have been established. When movie together with smell information is available, people have more real reality. Our group has studied odor presentation with visual and auditory information using an olfactory display [1]. In VR2007, we have demonstrated the game of cooking with scent using(More)
Awake surgery could be a useful modality for lesions locating in close proximity to the eloquent areas including primary motor cortex and pyramidal tract. In case with supplementary motor area (SMA) lesion, we often encounter with intraoperative motor symptoms during awake surgery even in area without positive mapping. Although the usual recovery of the SMA(More)
BACKGROUND Little is known about the pathogenesis and clinical course of fusiform compared with saccular aneurysms. The case of a ruptured fusiform aneurysm accompanied by dissection at the M2 portion of the middle cerebral artery (MCA) is reported, along with pathological findings. CASE DESCRIPTION A 41-year-old female presenting with subarachnoid(More)
Awake surgery for lesions in the non-dominant parietal lobe is rare. We report two cases of right parietal lobe glioma for which awake surgery was performed in order to avoid ataxie optique and hemispatial neglect due to injury in the superior and inferior parietal lobule, respectively. Among several tests to assess the dysfunction of spatial recognition,(More)
