If someone's hippocampus is destroyed, they lose the ability to form new (episodic) memories, and may lose some more recent old ones, but they certainly do not lose older ones. This is basic knowledge. > and that this ensemble it’s dedicated to that memory, or similar memories No - that's the exact opposite of what I said. My whole point was that a cortical column is NOT dedicated to a single memory (we'd run out of…

This is basic knowledge. Yes, like basic reading without digging into details. You must have heard about HM, since you’re saying all this. But here’s the facts: When H.M.’s remote memories were probed carefully, they turned out to be gist-li…
Re: Aging brains blend memories together instead of just forgetting them
#151There is 2006 paper "Polychronization: Computation with Spikes" E. Izhikevich. that describes one simulation they have done in silico and it explains how exactly distribution of activity happens and why you can't run out of memory. Basically the small group of neurons, say 10, can represent much larger amount of information say 1000 because they can fire in different orders, that is what they call poly-synchronous activity.
