StarLogo Simulation
Of Spiral Formation

•Amoebas are immobile at timescale of wave movement

•A fraction of patches are inert (grey)

•A fraction of patches has initial concentration of cAMP

•At each time step:

–chemical diffuses

–each patch responds to local concentration


	Ignores cell movement because several times slower than cAMP wave propagation
	At each step, patches share 50% of cAMP with 8 neighbors
