616,95 kr. Donald Kennedy President, Stanjord University Alnwst exactly a dozen years elapsed between the time I set aside (I thought temporarily!J my own interest in crustacean nervous systems and the arrival of an invitation from Konrad Wiese to participate in this symposium. The intervening years have plainly been productive ones for the field; indeed, I can only hope that there is no causal connection between its properity and my absence. Discontinuous contact with an intellectual venture, whatever disappointments it may present. does oifer one virtue; it provides a nwre dramatic. alnwst stroboscopic view of progress. To the lapsed practitioner, the rate of advance in crustacean neurobiology over the decade seems remarkable; equally remarkable is the number of able young researchers. many of them the scientific progeny of my colleagues from the "sixties" and "seventies" . How to summarize the changes they have wrought? Those of us who began working with crustacean nervous systems thirty years 090 or so were attracted by several features. First of alt there was a limited nwtor system with readily identifiable neurons. It was diJft.cult to look at those old methylene blue stains of Retzius and not want to do an experiment immediately! Kees Wiersma ojten did, and it was he who nwst persuasively called our attention to the advantages oifered by neuronal parsinwny in combination with stereotyped motor output patterning. Ted Bullock exploited these features in his elegant early experiments on cardiac ganglia.

Not unLike the photog~phic p~oduct they affo~d a topicaL ~eco~ of the goings-on, at pe~haps the expense of some inforrmation on detaUs. These Proceedings focus on the st~uctu~L and mechanistic aspects of vitamin B6-dependent enaymes; h01JJeve~, othe~ topics discussed ~nge f~om nonenaymic ~eactions of vitamin B6 compounds to nut~tionaL, medicaL, and even appLied indust~aL as pects.

1.145,95 kr. The field of neuroscience is experiencing a period of unprecedented growth. The range of ap proaches used to investigate the fundamental mechanisms underlying different aspects of somatosen sory perception has expanded substantially since the last International Symposium on Informa tion Processing in the Somatosensory System. Diversity of approach has become the hallmark of somatosensory research, and I believe that the impact of this diversity continues to be positive. of this symposium with previous symposia will show that researchers are employing Comparison an array of new methods and technologies and that they are offering new insights into old ques tions. The techniques range from studies of ionic channels, single unit recordings, functional brain imaging to psychophysics. A careful reading ofthe chapters reveals subtle and, on occasion, also obvious differences of opinion about experimental outcomes, approaches, and views. These differences are healthy signs of venture into new and uncharted territories. It is my hope that read ers will appreciate both the diversity of the research addressing somesthesis, and the personal commitment, enthusiasm, and scientific rigor of the participants who made this symposium and volume meaningful for all involved. We all look forward to tracking the progress of somatosensory research at our next Symposium at the turn of the century. OveFranzen November 1995 xv List of Contributors David T.

- Biological and Social Implications
1.126,95 kr. In 1992, a group of scientists including molecular biologists, microbiologists, population biolo gists, ecologists, human geneticists, moral philosophers and others met discussing the state of affairs regarding the deliberate or unintentional release of genetically modified organisms. The proceedings of this meeting were subsequently published by Birkhauser Verlag as Transgenic Organisms: Risk Assessment of Deliberate Release (K. Wohrmann and J. Tomiuk). Since then we have gained many new insights that are also worthy of discussion. And although other equally important scientific views on the release of genetically modified organisms exist, we have mainly concentrated on aspects of population biology and evolution. The results of a second meeting in 1995 are summarized here. We are grateful to colleagues and friends for their help in the translation, correction and review of the authors' contributions. We especially want to thank Jutta Bachmann, Donna Devine, Diana von Finck, Friedrich Laplace, Volker Loeschcke, Rolf Lorenz, Dave Parker and Trevor Petney. A grant (BMFT N' 0311035) from the Ministerium fUr Forschung und Technologie der Bundesrepublik Deutschland again made possible the continuation of this cooperative endeavour.
