In humans, appetite is affected by food experiences and food flavors. In the blowfly Phormia regina, we found that feeding threshold to sugar increased in the presence of the odor of D-limonene and decreased in the presence of the odor of dithiothreitol (DTT). Using these odors as representative nonappetitive and appetitive flavors, we demonstrated the role(More)
A sex difference in alpha-bungarotoxin binding capacity in the mouse amygdala has been demonstrated by quantitative light microscopic autoradiography. The difference persisted even under widely different steroid-hormonal environment. In addition, it was observed that the binding capacities in both sexes were reversibly activated by administration of either(More)
The alpha-bungarotoxin binding component in mouse brain was purified by affinity chromatography with toxin-Sepharose, gel-chromatography on Sepharose 6B, and ion-exchange chromatography with DE52 resin. The iodinated product of the last step produced one major and one minor band on sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). The(More)
We have shown a sex difference in the nucleus amygdaloideus medialis posterior (NAMP) of the mouse with respect to the binding capacity for alpha-bungarotoxin (alpha-BGT) under various steroid-hormonal environments. The present study describes histochemically the postnatal development of alpha-BGT binding capacity in the NAMP of the intact male and female(More)
A protein that binds alpha-bungarotoxin (alpha-BGT) was found in mouse brain and purified by means of Sepharose 6B column chromatography. The binding was inhibited by d-tubocurarine but not by atropine. This component was a glycoprotein with a molecular weight of 7 x 10(5) determined by gel chromatography, an apparent S value of approximately 11 determined(More)
Image restoration is an important topic in the area of image processing. Standard normalization methods are well known in which this problem is treated as the problem of optimization of the evaluation function. In this paper, we treat images degraded by a given shift-invariant blur function and additive Gaussian noise, and a method of image restoration is(More)
