Well, that would depend on what is meant by "almost". After all, as you form
new memories, no change is observed in the brain's structures etc. Looking
at the organism as a whole, you see that new memories/abilities are being
formed, but looking at the single neuron level, you don't know what changes
occur (and don't tell me that LTP is a model for memory).
