A Persistent Net
- A persistent net is a lot like a cell assembly.
- Here is an example net that can be proven to persist.

- If ABC neurons fire, the system will osicallate indefinitely
between ABC and DEF.
- Fatigue is essentially ignored by having fatigue less
than fatigue recovery.
- If you follow the math, the inputs to D, E, and F from A, B, and
C, are
all greater than 4 (the threshold is 4). (The reverse is
also true.)
- So, if you turn A,B,C on in one cycle, D, E, and F will fire in
the next, then back to ABC and so forth indefinitely.
- So, a persistent net (with appropriate inputs) is like
a state in an FSA.
- So, for each state there is a persistent net.
- It's also like a CA, because it persists after the initial
input ceases.
