    Notizen: [Auszug] IT has recently been claimed by Gibbs et al.1 that bombesin (BBS), like cholecystokinin (CCK), produces satiety in rats. However, their report ignores crucial evidence and lacks critical controls. First, there is good evidence that CCK suppresses feeding because it produces malaise. This has been ...

    Notizen: [Auszug] BECAUSE an injection of cholecystokinin (CCK) (or of the synthetic C-terminal octapeptide of CCK1) reduces food intake in the fasted rat, it has been suggested by Gibbs, Smith and colleagues2,6 that CCK may be a satiety signal. We present here evidence against this conclusion. To quote from ref 4, ...

    Notizen: [Auszug] In the experiment to be reported here, the time between two successive trains of electrically rewarding stimuli was varied to assess the effects of temporal spacing between them on a threshold of lever pressing. The subjects were three male albino rats of the Sprague-Dawley strain, weighing about ...

    Notizen: [Auszug] Fig. 1. Hesults of preliminary experiment on one animal. Crosses show the number of lever presses to extinction in successive 30-sec periods of normal extinction. Circles represent the number of lever presses in 30 sec of extinction during which a low intensity of repetitive stimulation was given, ...

    Notizen: [Auszug] ANY attempt to analyse the control mechanisms in the human operator is greatly facilitated if we can control all the information which is fed from the output back into the input. But whereas in most skills proprioception, which is resistant to such control, is of importance, in singing the role of ...

    Notizen: [Auszug] This comparatively simple situation, which obtains for the lighter molecules of the group, is in strong contrast with that for the heavier molecules, particularly for SnSe, SnTe and the lead compounds. In PbO, for example, the absorption region of longer wave-length (〉 2500 Å.) shows at least ...

    Notizen: [Auszug] Briefly, the technique described here is to inject into the stomach by way of a chronically implanted fistula small quantities of fluid (such as hyper tonic saline) in proportion as the animal itself drinks, say, water. In this way, the tonicity of the fluid arriving in the animal's stomach can be ...

    Notizen: [Auszug] IT is the purpose of this article to suggest a possible structural basis for shape recognition in the octopus. The octopus is now the best-investigated animal in respect of its discrimination of visual shape, and this is chiefly due to the work of N. S. Sutherland. This author has also put forward ...

    Notizen: [Auszug] SUTHERLAND, in a recent article1, offers an evaluation of my theory of the relation of the plexiform zone in the octopus to its shape discriminatory capacity2. A critique is made both on general grounds of plausibility and in relation to specific points of experimental evidence. Dr. Sutherland ...

    Notizen: [Auszug] Ninety-eight male Wistar rats (300-450 g) were housed and tested in individual wire mesh cages and maintained on a 12-h light/dark cycle. Tap water was available ad libitum and a maintenance diet of Purina rat chow was available for 2 h each day, beginning at 17.00 h. The rats were trained to drink ...
