Recently, we have often heard the terms "Wearable computing" and "Ubiquitous computing". Our expectation for the future of such new computing environments is growing. One of the characteristics of these computing environments is that they embed computers in our lives. In such environments, digitization of personal experiences will be made possible by(More)
In``Wearable computing'' environments, digitization of personal experiences will be made possible by continuous recording using a wearable video camera. This could lead tòàutomatic life-log application''. It is evident that the resulting amount of video content will be enormous. Accordingly, to retrieve and browse desired scenes, a vast quantity of video(More)
Cholecystokinin (CCK) is deeply involved in the control of learning and emotional behaviors. The authors characterize the behavioral properties of Otsuka Long Evans Tokushima Fatty (OLETF) rats, which lack the CCK-A receptor because of a genetic abnormality. In the Morris water-maze task, the OLETF rats showed an impaired spatial memory. In the inhibitory(More)
1. Subcutaneous or intrahypothalamic injections of capsaicin produce hypothermia in the neonate rat. Repeated injections with increasing doses of capsaicin result in unresponsiveness to this drug (capsaicin-desensitization). 2. Young rats aged 8–10 days which had received serial injections of capsaicin solution (a cumulative dose of 4.63 mg per animal) or(More)
Neuronal thermoresponsiveness in the preoptic and anterior hypothalamic (PO/AH) region of a bird and a mammal were compared in vitro by recording the activity of 48 units from ducks and 37 units from rats in tissue slices subjected to temperature changes. Warm-responsive units were found in similar proportions in duck and rat PO/AH slices. The average(More)
In conscious Pekin ducks adapted to hypertonic saline (1.9%) as drinking water, steady state secretion of the salt glands was established by continuous intravenous salt loading and the effects of hypothalamic thermal stimulation on salt gland activity and on the plasma concentrations of arginine vasotocin (AVT) and angiotensin II (AII) were observed.(More)
It has long been known that plasma interleukin (IL)-6 levels elevate during non-inflammatory, physico/psychological stresses such as immobilization (IMB) and electric foot shock (FS). We previously demonstrated that an IMB-induced rise in plasma IL-6 in the rat was caused, at least partly, by an increased production of IL-6 in hepatic reticulo-endothelial(More)
The effects of ambient and hypothalamic temperatures were studied on the hyperthermic responses to prostaglandins E1 and E2 (PGE1 and PGE2) injected intraventricularly in the unanesthetized rabbit. Hyperthermic responses to PGE1 observed at different thermal environments were approximately equal in magnitude and time course. However, the prevailing ambient(More)
