Preface
This volume contains papers submitted on the occasion of the fourth Reinhardsbrunn
Symposium on “Circumventricular Organs and Brain Fluid Environment: Molecular
and Functional Aspects” that was held in Leipzig, Germany, from March 24 to March
29, 1991. It provides a picture of the state of the art and of the perspectives opened
by new powerful approaches to the study of the structure and function of circumven-
tricular organs (CVOs). This term, inaugurated in the late fifties by Wolfgang
Bargmann and Helmut Hofer, is now well known and widely used in neuroscience.
In 1968, when Gunther Sterba (Leipzig) initiated the first international symposium
in Reinhardsbrunn on this topic, only a few specialists had been aware of the specific
peculiarities of these few and mostly microscopically small areas in the brain of
vertebrates. Today, it is widely accepted that at least some of the CVOs contain recep-
tors that are able to monitor fluctuations in blood-borne chemical signals and to
transfer that information to regulative centres located in other brain regions. Hence,
studies on the CVOs comprise many aspects, from cellular elements to the whole
organism: the accessibility of these organs for chemical signals, signal (ligand)-receptor
interactions, the transfer of information to distinct brain regions, the effects induced
in these brain regions and the influence on the regulation of body functions including
autonomic and behavioral alterations. Some of these aspects strongly depend upon the
microenvironment of the cells involved in this cascade of events. Therefore, the brain
fluid environment in its broadest sense is a central focus of the Reinhardsbrunn sym-
posia.
The composition of the fluids within the compartments of the brain is kept in
homeostasis by a variety of sophisticated regulatory mechanisms. Barriers within the
brain are the regulatory interfaces which have made the blood-brain barrier best
known.
From the beginning of the sixties there was a strong effort to identify neurosecretory
phenomena in the CVOs. The classic models of neurosecretion are peptidergic systems.
Until now, interest is focused on the release of mediators from cellular components of
the CVOs but also on the significance of peptides for central information processing
induced by or affecting the CVOs.
The 62 contributions to the four following sections of the symposium represent the
current work on this wide field of CVOs: “Microenvironment of the brain: blood -
interstitial fluid - CSF”; “Barriers within the brain: transport - exchange”; “Cir-
cumventricular organs: receptors and effectors”; and “Circumventricular organs and
brain fluids: systemic and behavioral aspects”. Taken together, an image arises of the
diversity of the engagement to contribute to the understanding of the above mentioned
aspects of brain work.
