                               Abstract

Since it has been suggested that the brain binds its fragmentary
representations of perceptual events via phase-locking of stimulated
neuron oscillators, it is important to determine how extended
synchronization can occur in a clustered organization of cells
possessing a distribution of firing rates. In order to answer that
question, we establish the basic conditions for the existence of a
binding mechanism based on phase-locked oscillations. In addition, we
present a simple hierarchical architecture of feedback units which not
only induces robust synchronization within and segregation between
perceptual groups, but also serves as a generic binding machine.
