To the untrained eye, all reed warblers may look alike. Anyone who takes a closer look will quickly realize that there is in fact an amazing spectrum of different ecological and adaptive strategies across the world ́s 53 species. Members of the reed warbler family have been models for this diversity in a large number of biological studies of avian lifestyles. Many of these have resulted in outstanding findings and set new standards in behavioural and evolutionary ecology. The authors rise to the challenge of determining how the members of the family have diversified by comparing their relationships and ecologies. This comparative approach runs like a thread throughout this book and touches ...
The investigation of the relationships between a behavior pattern and its underlying sensory and neurophysiological mechanisms in both man and animals dates back well into the last century. However, the concepts and findings of ethology and experimental psychology, together with an improved understanding of how the nervous system is organized and how neurons interact with each other, have only in the last 30 years laid the groundwork for an in-depth analysis. The many technological advances achieved in neurophysiology and neuroanatomy have also played an important role in this. The study of the neuronal bases of behavior - for which the term "neuroethology" has been coined - has thus become one of the central themes of neuroscience. Kenneth David Roeder, who died in 1979, was one of the pioneers of this field of research. It is to him that the contributions in this book are dedicated. K.D. Roeder was among the first to attempt to define the correlation between the natural behavior of an experimental animal and the activity of single sensory and nerve cells. The ques tions he asked, his experimental approach, and his fundamental discoveries are pre sented in an introductory chapter.
Advances in the quality and accessibility of computer graphics has provided new pictorial displays and the tools with which to control them. These new display technologies have focused interest on how to design the static and dynamic images they produce to ensure effective communication. This book, based on the conference on Spatial Displays and Spatial instruments held at the Asilomar Conference Centre in 1987, focuses on the geometry of this communication. It is intended to be a source book of theoretical analysis, experimental demonstrations and practical examples from a range of contributors interested in pictorial communication, from medical artists to astronauts. The book offers the theoretical background and practical guidance needed by designers of contemporary 2D and 3D graphical computer interfaces. Its major contribution lies in its outlining of the elements of human perception and motor control which underlie the geometric design of head-mounted graphics for virtual reality displays.
From recent developments in the rapidly growing area of neuroscience it has become increasingly clear that a simplistic description of brain function as a broad collection of simple input-output relations is quite inadequate. Introspection already tells us that our motor behavior is guided by a complex interplay between many inputs from the outside world and from our internal "milieu," internal models of ourselves and the outside world, memory content, directed attention, volition, and so forth. Also, our motor activity normally involves more than a circumscribed group of muscles, even if we intend to move only one effector organ. For example, a reaching movement or a reorientation of a sens...
This volume provides an overview of many of the issues that are currently of interest or importance to the vestibular and sensorimotor community, particularly as they relate to the perception and control of motion. Sections are included on vestibular transduction; studies of spatial orientation and three-dimensional organization; visual basis for the linear VOR and visual input to the VOR; perception of motion and position in hypergravity and hypogravity; neural processing and pathophysiology of the vestibular nuclei; stabilization of gaze and posture; and vestibular and cerebellar transmitters.
Given this situation, Professor Pugh's study of the plays' fortunes at the hands of the various schools of German literary scholarship from Schiller's day down to the present is useful both to literary scholars seeking orientation in the field and also to readers with a wider interest in German intellectual traditions."--BOOK JACKET.
Final report of the Sonderforschungsbereich "Kybernetik" 1969-83 from Munich University and Max-Planck-Institute. Contains 11 contributions restricted to the visual and motor systems. The delayed publication of results from 14 years of scientific endeavor is caused by the authors' intention to prepare comprehensive and balanced presentations instead of mere reports about recent findings. For those in the wide range of disciplines connected to cybernetic studies. Annotation copyrighted by Book News, Inc., Portland, OR
