Abstract: Temporal synchronization in neuronal assemblies has been linked to the functional roles of perceptual binding, sensory-motor integration, attention, and information coding. We report new evidence for a common underlying mechanism that uses specific temporal patterns of synchronized neuronal activity as a basis for conveying information. The temporal patterns of stimulus-related synchronized neuronal discharges are structured to closely resemble specific members of the Symlet wavelet packet family employed in a computational framework. Together, these results suggest that temporal patterns of synchronized activity may act as a parallel, distributed code for information through a mechanism computationally equivalent to wavelet packet analysis.
