Note: to get this to work with the
latest version of Java you need to add this website:
http://www.bio.miami.edu - to the list of exceptions in your java control
panel. This is a huge pain in the neck, I'm sorry.
Here is the simulation of a fluid neural network. Active squares (blue)
move and inactive squares (red), well, don't. Squares can be activated
either by self activation, in which they become active during a timestep
with a probability of about 1 in 200, or they can be activated by their
At low densities, such as the
example above which has eight 'ants', this periodicity
does not appear. One ant will become active at random, activate some,
none or all of it's neighbors, and then they will stop. They will stay
inactive for an interval of random length, until one becomes active at
Here is a look at a graph of a typical run. The y axis is the number of
active 'ants' plotted against each timestep.
Definitely not periodic, however, look what happens when
there are eighty ants instead of eight.
