Synfire chains as a neural mechanism for auditory grouping

More specifically, the network consists of several parallel chains of neurons in which the feedforward connections synapse with adjacent cells (figure 1). As a result of this topology, desynchronised spike trains at the input to the synfire chain become synchronised at the output. Also, the lateral connections of the network give rise to grouping by frequency proximity; spatially close inputs give rise to synchronised activity, where as spatially distant inputs do not.
