Synaesthesia is a strange sensory blending: synaesthetes report experiences of colours or tastes associated with particular sounds or words. This volume presents new essays by scientists and philosophers exploring what such cases can tell us about the nature of perception and its boundaries with illusion and imagination.
ill recent years, it has become clearly recognized that many behavioural disturb ances and psychiatric illnesses are intimately associated with alterations in neuroendocrine function. This volume is designed to provide a thorough, up-to date review of our current knowledge of the neuroendocrine correlates of altered behaviour in man and experimental animals. Particular emphasis has been focused on the mechanisms which may underlie the coupling of mental functions with endocrine changes and the possible common links in the central regulation of both endocrine and psychic activities. One of the main objectives of this book is to consider both the experimental and clinical approaches in studyin...
Unlike other human senses, the exact mechanisms that lead to our perception of flavor have not yet been elucidated. It is recognised that the process involves a wide range of stimuli, which are thought likely to interact in a complex way, but, since the chemical compounds and physical structures that activate the flavor sensors change as the food is eaten, measurements of the changes in stimuli with time are essential to an understanding of the relationship between stimuli and perception. It is clear that we need to consider the whole process - the release of flavor chemicals in the mouth, the transport processes to the receptors, the specificity and characteristics of the receptors, the transduction mechanisms and the subsequent processing of signals locally and at higher centres in the brain. This book provides a state-of-the-art review of our current understanding of the key stages of flavor perception for those working in the flavor field, whether in the academic or industrial sector. In particular, it is directed at food scientists and technologists, ingredients suppliers and sensory scientists.
This volume is devoted principally to the theme of behavioral develop ment. The study of ontogeny has attracted some of the most bitter and protracted controversies in the whole field of ethology and psychology. This is partly because the arguments have reflected more general and continuing ideological battles about nature and nurture. In the opening essay, Oppenheim shows how these debates have recurred in much the same form over the last century. His chapter also brings out a more worrying feature of such argument. He demonstrates that authors who are well known for their strongly held partisan views have written in much more balanced ways than is usually admitted. Although the ex cluded middle is familiar enough in academic argument, the dynamic tensions actually present in developing systems may be particularly prone to polarize debate about what is actually happening. This point is elegantly explored by Oyama in her essay on her concept of maturation.
Although serious interest in studying the role of central cho linergic processes in psychopathology is just beginning to emerge, experimental literature on the part played by cholinergic mechanisms in brain behavior. reiations is quite extensive. During the past thirty years, cholinergic research has contributed significantly to the characterization and differentiation of adaptive mechanisms in volved in input selection, perception, cortical, autonomic and behav ioral activation, learning, memory, and inhibitory control of behav ioral outputs. To say that dysfunction of one or more of these mech anisms may be at the root of neuropsychiatric illnesses such as schiz ophrenia would be stating t...
This book is a study of the use of monkeys as a tourist attraction in Japan. Monkey parks are popular visitor attractions that display free-ranging troops of Japanese macaques to the paying public. The parks work by manipulating the movements of the monkey troop through the regular provision of food handouts at a fixed site where the monkeys can be easily viewed. This system of management leads to a variety of problems, including proliferating monkey numbers, park-edge crop-raiding, and the sedentarization of the troop. In addition to falling visitor numbers, these problems have led to the closure or fencing in of many parks, calling into question the future of the monkey park as an institution.
