BACKGROUND/AIMS Previous studies using near-infrared spectroscopy (NIRS) have reported increases in both oxygenated hemoglobin (oxyHb) and deoxygenated hemoglobin (deoxyHb) during the paper version Trail Making Test (TMT), a neuropsychological test for evaluating cognitive and executive functions. We measured oxyHb and deoxyHb in the prefrontal cortex(More)
UNLABELLED We report on the successful identification of epileptic foci in two children with partial epilepsy using ictal magnetoencephalography (MEG). Case 1 is a 12-year-old male suffering with simple partial seizures with leftwards nystagmus. Ictal SPECT revealed a hyperperfusion area in the right lateral occipital area, and MRI revealed cortical(More)
Cell therapy using stem cells is awaited by stroke patients with impaired movement and cognitive functions, although intravenous alteplase-administration ameliorated outcomes of patients receiving the therapy within 3 h of onset. In this study, we explored the therapeutic effects of neural progenitor cells (NPC) upon middle cerebral artery occlusion (MCAO)(More)
BACKGROUND Juxta-dural ring aneurysms of the ICA have different clinical outcomes and risks for SAH, which are dependent on their position in the intradural or extradural space. The aim of this study was to reveal the precise location of such aneurysms by using CE-MRA. METHODS Contrast-enhanced MRA studies were performed in 21 patients with 24 juxta-dural(More)
We present a patient in whom magnetoencephalograms were successfully performed in presurgical and postsurgical evaluations. A 12-year-old boy with congenital porencephaly was admitted with refractory adversive seizures and frontal absence seizures. Ictal magnetoencephalographic dipoles with frontal absence seizures were located in the left frontal lobe,(More)
