OBJECTIVE To investigate the effect of interstimulus interval (ISI) on attentional enhancement of cortical activity in human somatosensory cortices. METHODS Somatosensory magnetic fields (SEFs) evoked by electrical stimulation of the right median nerve at ISIs of 0.5, 1, 3 and 5 s were recorded in two separate conditions by using whole head type(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)
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)
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)
OBJECTIVE Although the right prefrontal region is regarded as a silent area, chronic deficits of the executive function, including working memory (WM), could occur after resection of a right prefrontal glioma. This may be overlooked by postoperative standard examinations, and the disabilities could affect the patient's professional life. The right(More)
OBJECTIVE Dysphagia develops with low frequency in patients with dermatomyositis. Our objective was to determine the clinical and laboratory features that can estimate the development of dysphagia in dermatomyositis. METHODS This study included 92 Japanese patients with adult-onset dermatomyositis. The associations between dysphagia and clinical and(More)
