    Notes: [Auszug] THE discharge of cells in the visual cortex of two conscious, dark-adapted cats was recorded1. The depth at which the first unit showing a resting discharge was encountered by the microelectrode was taken as zero, and all recordings were made from units between this point and another lying not more ...

    Notes: [Auszug] Without loss of generality, let the O-spheres have diameter unity and let E(x) be the mathematical expectation of the number of spheres on an interval of length x. Suppose the O-spheres are forbidden to overlap each other or the end-points of the interval and that they are laid down sequentially ...

    Notes: [Auszug] IN this article we gather together experimental evidence supporting a recent idea about the electronic structure of body-centred cubic transition metals proposed by one of us1 and developed by the other*. A closely related theory has been given independently by Stevens8. We suggest, ...

    Binding in Hæmoglobin Azide as Determined by Electron Resonance: Theory of Electron Resonance in Ferrihæmoglobin Azide (1957)

    Notes: [Auszug] IN the preceding communication, ^-values were reported for ferrihsemoglobin azide. Here I give a theoretical interpretation of them, using the simplest plausible model for the five d electrons-that obtained by considering the matrix elements of the spin-orbit coupling, magnetic field energy and a ...

    A Theory of the Nature of Memory (1966)

    Notes: [Auszug] IT appears to be generally believed that no really simple theory of memory is possible, which is based on synaptic facilitation, is physiologically plausible and is in agreement with the most basic properties of conditioned reflexes1-3. This article describes a mechanism which, although undoubtedly ...

    Notes: [Auszug] What is the physiological basis of conscious thought in the mammalian brain ? A model is established of the neural organization underlying this process. It offers an explanation of the “stream of consciousness” and shows how it is possible for the memory trace to be delocalized, ...

    Aggressive behaviour of underyearling rainbow trout in simulated winter concealment habitat (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 49 (1996), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The behaviour of wild underyearling rainbow trout Oncorhynchus mykiss in concealment habitat in a laboratory stream aquarium at 2 and 6°C was recorded daily with an infrared video camera for 90 min over dawn. Aggressive behaviours (threat nips, nips and chases) were frequent during this time as fish entered concealment habitat. Aggressiveness varied widely among fish groups, with a range of 1 to 45 aggressive acts being initiated during a 90-min filming period. Larger fish initiated most of the encounters and removed a higher proportion of fish from concealment than did smaller aggressors. Thirteen per cent of the aggressive acts resulted in the recipient being completely removed from concealment habitat. The highest combined frequency of aggressive acts was 0.64 per visible fish per 10 min period and occurred at relatively low light levels (300 lx). The data suggest that when fish density is high, such as when habitat is limited, aggressive behaviour in winter may cause some underyearling salmonids to be excluded from concealment.

    Threadfin shad, Dorosoma petenense Günther, mortality: causes and ecological implications in a South-eastern United States reservoir (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 27 (1985), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Cold stress was identified as an important factor influencing both reservoir-wide mortality and impingement of threadfin shad, Dorosoma petenense, during the period October 1976 to April 1977 in Watts Bar Reservoir, Tennessee. Relative numbers and size frequency of impinged threadfin shad were similar to the relative numbers and size frequency of shad preyed upon by sauger, Stizostedion canadense, and skipjack herring, Alosa chrysochloris. This relationship implies that the factor mainly responsible for impingement, low temperature, also influences prey vulnerability. Threadfin shad made up 99% of the combined diet of sauger and skipjack herring from November until the threadfin shad disappeared in January. These predators did not readily switch to alternative prey in the short term, but by the next autumn 25–100% of the diet was alternative prey. Reappearance of threadfin shad the year following mass mortality and ability of the predators to vary their diet emphasize the resilient nature of some predator-prey systems.

    Notes: [Auszug] IT has been suggested that the agent responsible for scrapie, which affects sheep, has a very low molecular weight (∼2 × 105) and is probably a protein without nucleic acid1,2. It can infect goats, rats, mice or hamsters as well as sheep3,4. ...
