Abstract
Synchronization in coupled bifurcating neurons was studied from the view
point of the selective formation of cell assembly. The bifurcating neuron
is a simple chaotic neuron that exhibits chaotic inter-spike interval dynamics
via the addition of sinusoidal background oscillation. In this research,
we introduced the phase shift of the background oscillation and several
types of phase response to the input spike sequence. Sixteen coupled bifurcating
neurons with complete bidirectional coupling were numerically simulated
and their synchronized behaviors were analyzed. As a result, the formation
of chaotically synchronized cell assemblies for the phase shift value were
observed.
