Chapter 23: history of neuroendocrinology "the spring of primitive existence".
The history of neuroendocrinology is intimately related to one of the key questions, i.e. how does the brain manage to keep us alive and let our species survive? Neuroendocrinology, part of the answer to this question, is the discipline that studies hormone production by neurons, the sensitivity of neurons to hormones, and the dynamic, bidirectional interactions between neurons and endocrine glands. These interactions do not only occur through hormones, but are partly executed by the autonomic system that is regulated by the hypothalamus and that innervates not only the endocrine glands, but all our organs. The hypothalamus acts as a central integrator for endocrine, autonomic, and higher brain functions. The history of neuroendocrinology begins in 200 AD, with Galenus, who postulated that the brain excreted a residue from animal spirits (pituita), and continues into the last century, when researchers from different disciplines tried to understand how the brain regulates the vital functions of the body. Thanks to massive recent electronic publications of English and German scientific journals from the early 20th century we were able to rediscover fascinating articles, written in Europe before World War II, which showed that some of our most recent "innovative" concepts had in fact already been thought up some 50-100 years earlier. Apparently, World War II and the migration and exile of many researchers interrupted the development of concepts in this field and made rediscovery necessary. Our chapter gives an overview of the developments, both new and newly discovered.
