In recent years it has tended to become a sub-field in its own right, attracting workers of varied interests; it is also receiving increasing attention at the undergraduate level. Another recent development is an area which has come to be known as neuroethology. The problem for the neuroethologist is that much of behaviour is not reliable or 'reflex-like' in its expression. Communicative behaviour, on the other hand, often is, and here neurophysiology can make a significant contribution to our understanding of the underlying mechanisms. Some excellent texts on animal communication are available, as are collected essays on the neural substrates of specific behaviour patterns, but none of these provides a broad synthesis of concepts in neuro physiology and behaviour. The aim of this book is to draw attention to those areas where neurophysiology is relevant to the behaviourist. The book is not an introduction to animal behaviour or neurophysiology; some prior knowledge of these fields is assumed. It is the integration of these fields that we have attempted. 248 pp. Englisch.

This has resulted from the ubiquity of its distribution, and from the ease and sensitivity with which its activity can be measured. Unfortunately, these wide-ranging but often superficial experimental studies have been followed up by intensive and systematic investigations in only a few limited areas of the biochemistry and chemical pathology of alkaline phosphatase. The result has been the accumulation of a scientific literature of intimidating proportions, and the inevitable rediscovery of already known facts about the enzyme. Scientists are taught early in their careers that, in the words of Sir John Herschel, 'Hasty generalization is the bane of science. ' Nevertheless, moments arrive in all spheres of scientific activity when generalization becomes essential, to codify and to select from the mass of data already accumulated, and to provide starting points for new developments and new lines of investigation. This is especially true in a field such as alkaline phosphatase research, in which very real dangers exist that the seeds of fundamental understanding will be lost amidst an unexamined harvest of empirical observations. The history of the study of alkaline phosphatase provides several instances when valuable generalizations have emerged. Occasionally, the conclusions drawn on the basis of available evidence were wrong; more frequently, they have stood the test of further experimentation, and always, they have provided new insights into the nature and proper ties of this enzyme. 1008 pp. Englisch.
