The purpose of the present study was to develop a communication aid device utilizing event-related potentials (ERPs) for patients with severe motor disabilities. Preliminary experiments were performed on eight healthy volunteers to determine the optimal methods of presentation of visual stimuli and an off-line analysis of electroencephalography signals.(More)
With the progress of high-speed optical transmission and packet switching, a large capacity packet-based multi-media communication network is expected to spread rapidly. One of the key issues in these networks is the network routing that chooses the route to the destination for packet transmission in the network. In most previous work, the whole network is(More)
PURPOSE To correlate the signal intensity on magnetic resonance (MR) images in the posterior lobe of the pituitary gland with the vasopressin content. MATERIALS AND METHODS Fourteen rabbits were studied: 12 water-deprived rabbits (two each at 48, 74, 96, 120, 144, or 168 hours of deprivation) and two control rabbits. Sagittal T1-weighted MR images were(More)
