Conclusion
   - This talk is not about new evidence, but a proposal
       to find a system that represents CAs properly.
 
   - Take Home Points
      
	- CAs are persistent, learned, synchronous, and are 
            each a relatively small subset of all the neurons. 
 
	- As psychological phenomena, they represent short and
            long-term memories. 
 
	- We do not have good simulated neural models of CAs. (I'm 
            unaware of anyone who does.)
 
	- A good next model would solve the semantic net problem. 
 
	- Does that seem reasonable?
