Phys. Rev. Lett. 92, 118102 (2004) [4 pages]Hidden Neuronal Correlations in Cultured NetworksReceived 14 August 2002; revised 29 October 2003; published 19 March 2004 Utilization of a clustering algorithm on neuronal spatiotemporal correlation matrices recorded during a spontaneous activity of in vitro networks revealed the existence of hidden correlations: the sequence of synchronized bursting events (SBEs) is composed of statistically distinguishable subgroups each with its own distinct pattern of interneuron spatiotemporal correlations. These findings hint that each of the SBE subgroups can serve as a template for coding, storage, and retrieval of a specific information. © 2004 The American Physical Society URL:
