|
Program exaggerates slime
mold movement to illustrate streaming aggregation
|
|
Autonomous cell in center
releases cAMP at regular intervals (like a pacemaker cell)
|
|
Note at beginning
synchronized excitation and relativlye concentric waves
|
|
Soon begins to start
gathering into streams
|
|
Completely homogeneous
movement toward center is not a stable condition
|
|
Random perturbations cause
small heterogeneities to appear
|
|
They have no long-distance
vision, so they will turn toward nearby relaying cells
|
|
Cells tend to stick together
with stickiness that depends on cell density
|
|
Cell clumping is
autocatalytic or a positive feedback process
