During the discussion, Patrick Gill brought up an additional related paper:

Today several people asked me to send out a 2005 paper (Fusi, Drew, Abbott 2005, Cascade models of synaptically stored memories_)_ showing why a variety of memory maintenance mechanisms with different timescales are better than having just one or two simple memory maintenance mechanisms.  Here it is._  There's also a followup paper showing why it didn't matter that they used synapses with binary weighting in the 2005 paper:_  Stefano Fusi & L F Abbott  "Limits on the memory storage capacity of bounded synapses"  Nat Neuro 10 (4) April 2007 p 485.
