This volume contains summaries of most of the invited presentations given by lecturers and participants at the NATO Advanced Study Institute, "Develop mental Neurobiology of Vision," held in Rethymnon, Crete, Greece 18-27 Sep tember 1978. The purpose of this meeting was to enable a relatively small international group of scientists and students to hold discussions and to present their views on current problems in the field. It was intended that the results of the exchanges would be conveyed to others in the native countries of the parti cipants. An attempt was made to obtain broad representation of disciplines within the area of the Institute and this is reflected in the diversity of the chapters in this book. Considerable interest has been generated in recent years concerning the development and plasticity of vision. Perhaps not unexpectedly, along with the high level of activity in this field, there have been so me controversial findings.
