To clarify the exact anatomic relationship of electrically identified hand areas to the central sulcus, we constructed cortical surface renderings of magnetic resonance images (MRI) to locate the central sulcus accurately and measured the distances of stimulated points from the central sulcus and the Sylvian fissure. We obtained hand responses in 33(More)
Lectin-binding patterns in the accessory olfactory bulb (AOB) of the golden hamster were investigated histochemically with 21 biotinylated lectins. The AOB was divided into rostral and caudal halves according to binding patterns of 16 lectins, WGA, s-WGA, LEL, STL, DSL, BSL-II, DBA, SBA, BSL-I, VVA, SJA, PNA, ECL, UEA-I, Con A and PSA. The caudal half of(More)
Corpus callosotomy is a well established procedure for the treatment of intractable epilepsy. However, this is the first clinical report of surgical division of the corpus callosum in Japan. Four patients with refractory seizures suffering from Lennox-Gastaut syndrome underwent anterior partial corpus callosotomy. Their seizures consisted of absences,(More)

1 Introduction Selecting the surgical candidate for medically intractable epilepsy, detection and localization of seizure focus and cerebral functions are essential for diagnosis, for localization of surgical treatment and for prevention of surgical complications. Due to the limitations of noninvasive evaluations, invasive examinations, such as chronic ECoG(More)
The efficacy and possible side effects of thromboxane A2 (TXA2) synthetase inhibitor in the treatment of cerebral vasospasm after subarachnoid hemorrhage (SAH) were assessed for 24 patients who presented with grades I to IV of the Hunt and Hess classification. All patients underwent aneurysmal clipping within 48 hours after SAH. Postoperatively, TXA2(More)
During vertebrate development, the central nervous system (CNS) has stereotyped neuronal tracts (scaffolds) that include longitudinal and commissural axonal bundles, such as the medial longitudinal fascicle or the posterior commissure (PC). As these early tracts appear to guide later-developing neurons, they are thought to provide the basic framework of(More)
We have developed a translucence stereoscopy method for displaying the distribution of multiple interictal epileptiform discharges within the intracranial space. The epileptiform discharges, measured using a whole-head magnetoencephalography system, were modeled by a least-squares method to obtain the equivalent current dipoles. The dipoles were located in(More)
A 57-year-old male with primary intracranial malignant melanoma who survived 9 years and 6 months is reported. He underwent surgical removal of the tumour three times during the decade 1978 to 1988, and received chemo-immuno-radiotherapy during that time. Acute tumour growth, suggesting tumour dissemination, was seen in the CT scans after the third removal(More)
Although osteoma of the paranasal sinus is comparatively common, involvement of the sphenoidal sinus region is extremely rare. Lame reported that a total of twelve cases had been described in the European literature since 1800. Mikaelin, Kulczynski and Dolan, since then, described three cases. This paper deals with two surgical cases of sphenoidal sinus(More)

1 Introduction Equivalent current dipole (ECD) analysis for mag-netoencephalogram (MEG) has been useful in screening the localization of the epileptogenic zone, even though MEG was recorded in the interictal period [1] [2]. However, it requires several mathematical restrictions and often fails to estimate confidential current sources. Therefore the(More)
