Abstract

Organotypic cocultures of dorsal root ganglia and spinal cord from embryonic rats provides direct access to spinal interneurons in a culture system in which the cytoarchitectural organization of the spinal cord slice is maintained. This preparation was used to investigate the possible induction of rhythmic behaviour at different times of development in vitro. Spontaneous rhythmic bursts induced by coapplication of strychnine (1 microM) and bicuculline (20 microM) were observed with patch-clamp recordings from ventral interneurons. Ventral horn interneurons consistently developed a very regular pattern of activity which was superimposed on a background of sustained synaptic activity. The pattern of the spontaneous bursting following application of strychnine and bicuculline showed a developmentally regulated difference in frequency between two distinct stages of in vitro development.
