How the Leopard Got Its Spots

The Human Computer
Spatial Patterning and lateral inhibition
Take a coin and flip it.
If it’s: Heads, stand up.  Tails, remain seated
If you are standing, you are expressing A in high quantities. If you are sitting, you are not.

Those of you making protein A (standing) are also emitting another substance,
I which inhibits your neighboring cells from expressing A.

When I say “go”
- if your two neighbors are standing…. You must sit down
- if your two neighbors are sitting….  You must stand up
- if one neighbor is standing and the other sitting… You choose

  …local rules lead to the emergence of a global pattern!
