Hm. I've always commented on my (temporarily) non-retrievable memories as, "The data is still in there, it's the retrieval mechanism that degrades if not used." And, sure enough, in most cases the memory returns in a day or so, even if you don't think hard about it. (There are cases where the memory doesn't come back, as if it was actively erased or was never in long term memory in the first place. Also, as I pass eighty, I find it increasingly difficult to memorize things, and I forget recent events more readily. But I remember decades old events about as well as I ever did.)

So, my first response to your comment about the memory not being in the synapses was to agree with you. But I also agree with your respondent, so, hm.
