    Abstract

    Understanding the neural code of cultured neuronal networks may help to forward our understanding of human brain processes.The most striking property of spontaneously firing cultures is their regular bursting activity, a burst being defined as synchronized firing of groups of neurons spread throughout the entire network. The regularity of bursting may change gradually with time, typically being stable over hours (Stegenga et al. 2008). Cultured cortical networks composed of many thousands of neurons show bursting behavior starting from the end of the first week in vitro. Bursts can be characterized by both intraburst parameters (burst shape, maximum firing rate, leading and trailing edge steepness, etc.) and interburst parameters (statistics, stability of burst rates) (Van Pelt et al. 2004; Wagenaar et al. 2006). Not only the temporal burst characteristics develop with time. Also, spatial burst propagation patterns, socalled ‘’burst waves’’, change with age of the network.
