A rating scale for assessing troublesome behavior associated with dementia illnesses was developed. This instrument, named the troublesome behavior scale (TBS), is designed to be completed by family and professional caregivers. It is comprised of 14 questions assessing a variety of types of disruptive or burdensome behavior. Two of the 14 questions differ(More)
INTRODUCTION Studies of cerebral hemodynamics during motor learning have mostly focused on neurorehabilitation interventions and their effectiveness. However, only a few imaging studies of motor learning and the underlying complex cognitive processes have been performed. METHODS We measured cerebral hemodynamics using near-infrared spectroscopy (NIRS) in(More)
The aim of this study was to clarify the topographical localization of motor-related regional hemodynamic signal changes during motor execution (ME) and motor imagery (MI) by using near-infrared spectroscopy (NIRS), as this technique is more clinically expedient than established methods (e.g., fMRI). Twenty right-handed healthy subjects participated in this(More)
We consider an addition of the term which is a square of the scalar curvature to the Einstein-Hilbert action. Under this generalized action, we attempt to explain i) the flat rotation curves observed in spiral galaxies, which is usually attributed to the existence of dark matter, and ii) the contradicting observations of uniform cosmic microwave background(More)
INTRODUCTION The aim of the present study was to investigate how the speed of observed action affects the excitability of the primary motor cortex (M1), as assessed by the size of motor evoked potentials (MEPs) induced by transcranial magnetic stimulation (TMS). METHODS Eighteen healthy subjects watched a video clip of a person catching a ball, played at(More)
A rating scale measuring care status related to assistance with basic ADL for demented patients was developed. This instrument, named the ABCD, is designed to be completed by family and professional caregivers, and consists of two subscales assessing the level of difficulty of help with the ADL (difficulty scale) and the reasons why assistance is needed(More)
