We demonstrated the exact location of the somatotopic area of the corticospinal tract in the internal capsule. Ten healthy subjects participated in this study. We used the imaging technique that combines functional magnetic resonance imaging and diffusion tensor tractography. In order to reduce erroneous elements while image processing, we used the(More)
We describe the fabrication and use of an in vitro wounding device that denudes cultured epithelium in patterns designed to leave behind strips or islands of cells sufficiently narrow or small to ensure that all the remaining cells become rapidly activated and then migrate, dedifferentiate, and proliferate in near synchrony. The design ensures that signals(More)
A primary characteristic of autism, which is a neurodevelopmental disorder, is impaired social interaction and communication. Furthermore, patients with autism frequently show abnormal social recognition. In mouse models of autism, social recognition is usually assessed by examining same-sex social behavior using various tests, such as the three-chamber(More)
A series of derivatives for both the arthropod and mollusc hemocyanin biopolymers has been prepared; the derivatives contain a small fraction of electron paramagnetic resonance-detectable half-met [Cu(II) CU(I)] sites dispersed among the non-detectable oxy binuclear copper active sites. Upon deoxygenation, large changes in the electron paramagnetic(More)
Because Broca's area and Wernicke's area in the brain are connected by the arcuate fasciculus, understanding the anatomical location and morphometry of the arcuate fasciculus can help in the treatment of patients with aphasia. We measured the horizontal and vertical curvature ranges of the arcuate fasciculus in both hemispheres in 12 healthy subjects using(More)
