The workshop entitled "The Role of Cell Interactions in Early Neurogenesis" was held at the Institut d'Etudes Scientifiques in Cargese, Corsica on May 29th to June 3rd, 1983. The setting was ideal for a small meeting whose purpose was to generate as much discussion as possible between the various participants. One of the major topics of this conference was neural induction, that is, the first step in neurogenesis. Neural induction remains poorly understood at the molecular level as compared to the sub- sequent steps of neuronal migration and differentiation. It thus appeared important to...
