Using near-infrared spectroscopy (NIRS) techniques, it is possible to examine bilateral motor cortex oxygenation during a static motor task. Cortical activation was assumed to be reflected by increased oxygenation. The purpose of the present study was to examine the time course of oxygenation in the bilateral motor cortex during a low-intensity handgrip(More)
This study evaluated the role of central command in the regulation of common carotid artery blood flow and middle cerebral artery mean flow velocity (V(MCA)) at the onset of arm exercise. Eleven young women performed 2 min voluntary elbow flexion and extension exercise with no load (VOL) that was considered to activate both central command and the muscle(More)
In a previous study, we indicated that human interferon (IFN)-alpha (IFN-alpha, 6 x 10(4) IU/kg, i.v.), but not human IFN-beta or -gamma, prolonged the immobility time of the forced swimming test in mice. In this study, we investigated the mechanism of the effect of human IFN-alpha. None of the mouse IFNs tested (IFN-alpha/beta, IFN-beta, and IFN-gamma, 3 x(More)
