Multiple unit activities (MUA) in 307 brainstem sites were recorded by chronically implanted electrodes in cats, using a polygraph with 4 channel MUA recording units. During transition from waking to slow wave sleep, at 15 sites including the medial preoptic area (11), the diagonal band of Broca (2) and medial anterior hypothalamic area (2), consistently… (More)
OBJECTIVES We quantified the rCBF and regional vascular reserve (CVR) in adult patients with moyamoya disease before and after surgery using IMP I 123 SPECT. METHODS The patient population included 5 adult patients with ages at presentation ranging between 23 and 42 years. One patient had stroke, whereas 4 patients had transient ischemic attacks. … (More)
A case of malignant astrocytoma in the frontoparietal parasagittal region with transgression into the overlying dura mater and the skull is presented. Spontaneous transdural extension of a glioma is an extremely rare growth pattern. A mode of transdural extension of this tumor is discussed and related reports are reviewed.
Several PC-based image processing systems developed for experimental measurements in our laboretory are described in this paper. They are a motion measurement system, motion picture analysis systems and color image processing systems for robotics. High quality with low cost image digitizing boards become available to use, and a capacity of RAM boards grows… (More)
