Abstract:
We present experimental results of pattern formation in a
forced system of coupled cellular oscillators. The response of
spatially distributed cultured cardiac cells to a periodic forcing
of electrical stimulation is examined by fluorescent methods.
We show that a periodic forcing can lead to the coexistence of
2:1 and 1:1 synchronization modes within the cellular monolayer,
and that the mode sites are distributed into spatially localized domains
instead of being randomly spread over the monolayer.
