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)
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)
The effects of recombinant mouse stem cell factor (rmSCF) on paired-pulse facilitation (PPF) and long-term potentiation (LTP) in the mossy fiber (MF)-CA3 pathway were examined in mouse hippocampal slices by recording field EPSPs. When PPF was measured before and 30 min after tetanic stimulation, the initial PPF positively correlated with the amplitude of(More)
Organic thin-film solar cells with a conducting polymer (CP)/fullerene (C 60) interpenetrating heterojunction structure, fabricated by spin-coating a CP onto a C 60 deposit thin film, have been investigated and demonstrated to have high efficiency. The photovoltaic properties of solar cells with a structure of indium-tin-oxide/C 60 / poly(3-hexylthiophene)(More)
The solvent vapor treatment (SVT) for poly(3-hexylthiophene) (PAT6) films and its application to interpenetrating heterojunction organic solar cells have been studied. It was found that SVT could improve the crystallinity and electrical characteristics of the PAT6 films. We fabricated organic solar cells with an interpenetrating structure of PAT6 and(More)
