Abstract
Participants in the workshop on Sensory Anatomy and Physiology discussed many issues pertaining to aspects of continuing work on cetacean brain material. All agreed that among the major problems of carrying-out research in this area was one of inability to obtain adequately and properly prepared brains and other tissues. There especially is need for better communication and networking among scientists in the laboratory and the field relating to availability of material and special preservative and fixative techniques such as for electron microscopic studies or immunocyto-chemical analyses. Obviously, beached, dead specimens are of little use in specialized studies other then for the most gross observations. Brain material must be fresh and quickly perfused for serious microscopic studies. Perfusion must be carried-out to adequately fill the vast rete mirabile complex of the vascular network that is interposed between main blood vessels and the brain. Unfortunately, such perfusions may make the material less useful for many other types of studies such as bacteriological and various chemical analyses. In many cases investigators interested in the body as a whole are reluctant to allow a perfusion that enters the primary circulation and thereby makes many other types of studies impossible.
