Biocybernetics Of Vision: Integrative Mechanisms And Cognitive Processes by Cloe Taddei-ferretti Pdf

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.

Vision by Carlo Musio Pdf

The light sense is conceivably the key sense in both the animal and the plant kingdom. Vision research, undoubtedly a fast-growing field, is providing impressive results OCo thanks to modern theoretical and methodological advances. The approach of biophysics and neuroscience seems to be of great benefit and, for this reason, the present book gives an outline of recent acquisitions and updated advanced methods concerning this approach. Visual mechanisms and processes are analysed at several (molecular, cellular, integrative, computational and cognitive) levels by different methodologies (from molecular biology to computation) applied to different living models (from protists to humans, via invertebrates and lower vertebrates). Contents: The Optics of Animal Eyes (M F Land); Rhodopsin-Like Proteins: The Universal and Probably Unique Proteins for Vision (P Gualtieri); The Molecular Design of a Visual Cascade: Molecular Stages of Phototransduction in Drosophila (R Paulsen et al.); Molecular Changes During Primary Visual Pathway Development (K L Moya et al.); Color Vision and Retinal Randomness of the Japanese Yellow Swallowtail Butterfly, Papilio Xuthus (K Arikawa et al.); Patch-Clamping Solitary Visual Cells to Understand the Cellular Mechanisms of Invertebrate Phototransduction (C Musio); Phototransduction in Retinal Rods and Cones (Y Koutalos et al.); Formation of OC ONOCO and OC OFFOCO Ganglion Cell Mosaics (L M Chalupa); Endogenous Nitric Oxide Modulates Signal Transmission from Photoreceptors to On-Center Bipolar Cells in the Rabbit Retina (B Lei & I Perlman); Now You See It, Now You Don't: Shunting Inhibition in Early Vision (L Borg-Graham et al.); Visual Perceptual Learning (N Berardi & A Fiorentini); Functions of the Primate Temporal Lobe Cortical Visual Areas in Invariant Visual Object and Face Recognition (E T Rolls); Vector Code in Neuronal Networks (E N Sokolov); and other papers. Readership: Scientists and postdoctoral students in neurosciences, biophysics and physiology."

Downward Processes In The Perception Representation Mechanisms - Proceedings Of The International School Of Biocybernetics by Cloe Taddei-ferretti,C Musio Pdf

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.

Neuronal Bases and Psychological Aspects of Consiousness by Cloe Taddei-Ferretti Pdf

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.

Macromolecular Interplay in Brain Associative Mechanisms by Anna Neugebauer Pdf

This volume looks at the associative mechanisms of the brain, particularly of the cortico-limbic and diencephalic systems, and also at the macromolecular effects on them, by integrating the contributions of various disciplines converging on one subject and from different points of view. It addresses the question of how so many different activity levels — the biochemical, physiological, and psychological ones — interact in integrative processes. The topics treated include brain reverberating systems and associative phenomena; long-term potentiation, learning, and memory; gene activity and brain activity; and gene expression and information processing during sleep.

Neuronal Processing of Optic Flow by Anonim Pdf

When we walk, drive a car, or fly an airplane, visual motion is used to control and guide our movement. Optic flow describes the characteristic pattern of visual motion that arises in these situations. This book is the first to take an in-depth look at the neuronal processing strategies that underlie the brain's ability to analyze and use optic flow for the control of self-motion. It does so in a variety of species which use optic flow in different behavioral contexts. The spectrum ranges from flying insects to birds, higher mammals and man. The contributions cover physiological and behavioral studies as well as computational models. Neuronal Processing of Optic Flow provides an authoritative and comprehensive overview of the current state of research on this topic written by a group of authors who have made essential contributions to shaping this field of research over the last ten years. Provides the first detailed overview of the analysis of complex visual motion patterns in the brain Includes physiological, behavioral, and computational aspects of optic flow processing Highlights similarities and differences between different animal species and behavioral tasks Covers human patients with visual motion deficits Enhances the reader's understanding with many illustrations

Emotions, Qualia, and Consciousness by Alfred W. Kaszniak Pdf

The experience of emotion is a ubiquitous component of the stream of consciousness; emotional qualia interact with other contents and processes of consciousness in complex ways. Recent research has supported the hypothesis that important functional aspects of emotion can operate outside the conscious awareness. Primary types of emotions are found in animals, while secondary, more complex types are involved in interpersonal relationships. Emotions both influence genetic repair mechanisms of individuals and are responsible for group behavior. Many scholars and scientists believe that no scientific or philosophic account of consciousness can be complete without an understanding of the role of emotion. Contents: Emotion and Consciousness: Current Research and Controversies (A W Kaszniak); The Nature of Typical Emotions (A Ben-Ze''ev); Emotions Associated to Cognitive Revision as a Basis for Values (P Livet); Neuro-Affective Processes and the Brain Substrates of Emotion: Emerging Perspective and Dilemmas (J Pankseep); Imagery and Emotion: Information Networks in the Brain (P J Lang); Hemispheric Asymmetries in Representation and Control of Emotions: Evidence from Unilateral Brain Damage (G Gainotti); Hierarchical Organization of Emotional Experience and Its Neural Substrates (R Lane); Metal Representations, the Reticular Activating System and Emotions (B Cabott); Antecedents and Functions of Emotion Episodes (N H Frijda); The Communication of Emotion (U Hess); The Mental Representation of Romantic Jealousy: A Blended Emotion (and More) (D J Sharpsteen); and other papers. Readership: Postdoctoral students and researchers in biocybernetics, neurosciences, cognitive sciences and psychology.

Vision: Images, Signals and Neural Networks by Jeanny Hérault Pdf

At the fascinating frontiers of neurobiology, mathematics and psychophysics, this book addresses the problem of human and computer vision on the basis of cognitive modeling. After recalling the physics of light and its transformation through media and optics, Hérault presents the principles of the primate's visual system in terms of anatomy and functionality. Then, the neuronal circuitry of the retina is analyzed in terms of spatio-temporal filtering. This basic model is extended to the concept of neuromorphic circuits for motion processing and to the processing of color in the retina. For more in-depth studies, the adaptive non-linear properties of the photoreceptors and of ganglion cells are addressed, exhibiting all the power of the retinal pre-processing of images as a system of information cleaning suitable for further cortical processing. As a target of retinal information, the primary visual area is presented as a bank of filters able to extract valuable descriptors of images, suitable for categorization and recognition and also for local information extraction such as saliency and perspective. All along the book, many comparisons between the models and human perception are discussed as well as detailed applications to computer vision.

Neuronal Coding of Perceptual Systems by Werner Backhaus Pdf

Neuronal coding of information coming from external and internal environments and transducted by sensory receptors constitutes a basic biophysical problem. After the coding phase, such information orients organism responses, shaping complex behavioural patterns. The characteristics of both neurons (interneurons with re-entering connections, latency times, filter bandwidth with respect to input signals, logic operations on multiple convergent signals) and neuron nets (reverberating nets, feedback/feed-forward connections, oscillations due to endogenous activity patterns) are important for coding mechanisms. Neuronal coding is implied also in the higher phases of information processing linked to consciousness, when neuronal activity patterns are related to perceptual mental representations.
