Afferent and Intrinsic Organization of Laminated Structures in the Brain

These are the records of the 7th International Neurobiology Meeting, which was held at the Max Planck Institute of Biophysical Chemistry in September 1975. The Neurobiology meetings started about 20 years ago with the aim of bringing together scientists working on the nervous system with different methods such as anatomy, physiology, endocrinology and biochemistry, and to create a common approach to what is now called "neurosciences". When these meetings were in­ augurated by a few it was decided not to found a society, but to keep them informal and to leave it to the respective host to decide on the program and formate. At the end of each meeting, a small informal committee chose the next host and organizer. In such a way, meetings were held in various places (Amsterdam, Kiel, Stockholm, Oslo, Oxford) and on different subjects such as neuroendocrinology, the limbic and the visual systems, on excitatory and in­ hibitory synaptic mechanisms. The contributions to some of the meetings were published. Also, this time it was discussed whether - in view of the growth, the in­ creasingly structured organization and, at the same time, diversification of the neurosciences - another meeting of this sort should be held. It became during this discussion, that the tradition of these meetings should be con­ tinued, since they can be considered complementary to the formal, all embra­ cing congresses, as an informal gathering of neuroscientists interested in the borader aspects of one particular subject of this still growing discipline.
