But do they keep the memories when you pull out the electrodes? I think this effect is extremely interesting. One of my friends got a new lease on life with a pacemaker for Parkinson's Disease. It's wonderful, but the basic idea is not new. Wilder Penfield found this effect in 1951.

I don't think it will work with Alzheimers patients, though. A lot of the brain cells are just gone.

You're probably right about the Alzheimer's sufferers, unless early stimulation might prevent the loss of those brain cells.

I wonder if that process helps remember specific things (like where I put my billionaire uncle's will), or do the recovered memories spill out at random? Looks sort of random, so far.

An electrode is a pretty blunt object and neurons don't come with labels. Penfield found that the memories were random.
