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)
Nonenhancing intrinsic brain tumors have been empirically treated with a strategy that has been adopted for World Health Organization (WHO) grade II gliomas (low-grade gliomas: LGGs), even though small parts of the tumors might have been diagnosed as WHO grade III gliomas after surgery. However, the best surgical strategy for nonenhancing gliomas, including(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)
OBJECTIVE The arcuate fasciculus has been recognized as an important pathway for language processing. Brain tumors located in proximity to the fasciculus frequently cause preoperative language impairment, and in some cases, no language recovery occurs after tumor resection. No predictive value has been presented for possible postoperative language recovery(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)
A 5-year-old male presented with scrotal migration of the catheter from a ventriculoperitoneal shunt manifesting as left scrotal swelling 4 months after implantation. Surgical obliteration of the patent peritoneal processus vaginalis that forms a corridor from the peritoneum to the scrotum was performed to avoid shunt malfunction. Review of the 26 reported(More)
