High Dilution Effects On Cells And Integrated Systems - Proceedings Of The International School Of Biophysics
Inbunden, Engelska, 1998
2 215 kr
Skickas inom 5-8 vardagar
High dilution effects constitute a major problem on the frontier of biophysics. The reported effects on simple and complex biological systems range from in vitro and in vivo models to cellular metabolism regulation, the immune system, the nervous system, intoxicated organs and organisms, and developmental models. The physical properties of high dilutions have been considered, such as the organization properties of water molecules in the presence and after the presence of solute molecules, the energy characteristics of empty and full water clusters, and their dynamical interactions with proteins. Among the mechanisms responsible for the high dilution effects, a non-molecular transfer of information has been hypothesized.

Biophysics Of Photoreception: Molecular And Phototransductive Events
Inbunden, Engelska, 1998
2 303 kr
Tillfälligt slut
This is the first volume of new book series on biophysics and biocybernetics, initiated by the Istituto Italiano per gli Studi Filosofici.A main problem in biophysics is the interaction of light information with functional living structures, in order to shape the organism's behaviour. Although the processes of photoreception and phototransduction are articulated in various ways in different living beings — as it is seen in the subdivision of the topics in this volume on microorganisms, invertebrates, and vertebrates — general ways of light signal reception and transduction through light energy, i.e., photosensitive molecule interactions, could be observed. Highly sophisticated advanced techniques are employed in this research field.

Biocybernetics Of Vision: Integrative Mechanisms And Cognitive Processes
Inbunden, Engelska, 1998
2 372 kr
Tillfälligt slut
Visual cognition is an important area of biocybernetics. It ranges from the filtering processes of early vision to the structural and functional organization of the visual centres, as well as, in higher animals, to the neuronal plasticity, the decision-making rules, the effect of noise, the role of attention, the ambiguity of patterns, and the time dimension. All these factors contribute to the cognitive interpretation of visual sensation that takes place in visual perception. A side field is machine vision, in which the signal processing known from animal vision is applied to the mobile robots responding to light stimulation.

Neuronal Bases And Psychological Aspects Of Consciousness - Proceedings Of The International School Of Biocybernetics
Inbunden, Engelska, 1999
2 827 kr
Tillfälligt slut
For a few decades, the puzzle of consciousness, which for centuries was analysed by philosophers, has been finding a wide interest in the scientific field, where previously it was not entitled to be a member. It has become one of the most-debated problems in the cognitive sciences. The anatomical bases, neurophysiological correlates and elementary mechanisms underlying complex processes arising with consciousness have been compared with the psychological (perceptive, cognitive, volitive, emotional) aspects of conscious expressions, in normal and pathological conditions. Various theories, which attempt to fit systematically and coherently neural and psychological data, have been debated, proving the emergence of the phenomenon of consciousness.

From Structure To Information In Sensory Systems - Proceedings Of The International School Of Biophysics
Inbunden, Engelska, 1998
3 007 kr
Tillfälligt slut
This book is a sequel on the topics of photoreception and phototransduction covered by Volume I of the series (Biophysics of Photoreception: Molecular and Phototransductive Events), adding the analysis of two other modalities of sensory reception and transduction — the chemical and mechanical ones, which are phylogenetically older. This characterization results not in a succession of three different and uncorrelated moments, but in a fruitful confrontation between experts which usually act separately and in an integration between various particular knowledges. This approach highlights the basic strategies common to different sensory modalities and specializations, as well as the ecological adaptations of each of them.

Downward Processes In The Perception Representation Mechanisms - Proceedings Of The International School Of Biocybernetics
Inbunden, Engelska, 1998
3 359 kr
Tillfälligt slut
Perception is the first step in the whole of the cognitive processes (attention, learning, memory, categorization, imagery, intuition, inference, comprehension, thought, judgement, expression) which culminate in the reasoning activity and to which emotions make a contribution. The production of perception representations is correlated with the perception events. Such perception representations occur by means of the contribution of two kinds of factors: sensory signals which reproduce the spatio-temporal characteristics of the receptor modifications, and interpretation of the intrinsic ambiguity of such signals by means of unconscious inferences. Various interactions intervene between bottom-up signals from peripheral receptors and top-down signals from higher centres.
