Neuronal Cell Cultures.

A week-long conference was organized to survey the contribution that cell culture methodologies have made to neurobiology. Developmental questions were prominent in the presentation with emphasis on trophic materials that regulate neuronal survival and differentiation. Neural network and synaptic interactions could be advantageously studied in the cultural neuronal preparations. Both invertebrate and vertebrate material develops well in vitro. A broad range of mammalian central nervous system structure are now available for detailed study under the relatively high degree of experimental control provided by cell culture techniques.
