It could be but do you think it really does? Couldn't there still be redundant 
of the same information on many different synapses? The reason I ask this is
because of related work not on LTD but on Long Term Potentiation, in particular

the work of Dan Madison and Erin Schuman In the January 28 1994 issue of 
They found that LTP spreads out over a large area so you have lots of copies
of the same thing. Neural Net expert Terrence Sejnowski said at the time
"Instead of thinking of a synapse as representing a piece of information you

can now begin thinking of a population of potentiated synapses acting together".
Could the same thing be true for Long Term Depression?
