Abstract. The intrinsic mechanisms underlying burst generation in vitro are generally well understood. However, how these mechanisms are implemented under in vivo conditions is still not clear. Pyramidal cells within the Electro Lateral Lobe of the electric fish have a well defined burst mechanism in vitro which is based on a somato-dendritic interaction. Surprisingly, in vivo recordings from these cells do not show any of the characteristics associated with bursting found in vitro. We propose a computational model that can explain these differences.
