This 9-3 heteroclinic state is characterized by the intermittent appearance of a stable pattern (usually 9 cells surrounding 3 cells) which eventually disorganizes and is followed by irregular behavior.
Cells Segmented
The image shows an
example of the stable 9-3 pattern. The accompanying movie shows
the disorganized behavior that occurs between stable patterns.
The unstable is characterized by distortion and movement towards
the center by cells in the outer ring. The other cells in the
outer ring appear to compensate for the resulting gaps by splitting.
Because this movie was made at the segmentation phase, the cell
colors do not correspond in successive frames.
Time-Lapse
The time-lapse of the cell centers during the segmentation
phase shows disorganized motion in the center. The outer ring
is still distinguishable during the motion.
Time Line
The time line representation
of the process shows that a cell dissipation is almost always accompanied by
a split in the next frame as the system tries to maintain the
spacing among cells.
