This approach is outdated. Take a look at *The Invention of Memory: A New
View of the Brain* by Israel Rosenfield, Basic Books, 1988.
Rosenfield contrasts the brain with a computer, in which data remains dead
and (except for an external accident) unchanging until someone reads it.
But brains are fundamentally dynamic. Neurons don't sit still. Neural
"memory" would have to be continuously recreated in the human brain, thus
compromising the accuracy of our recollections. This model is sometimes
called "neural darwinism," the idea being that millions of impulses inflow
on each neuron, and only some get selected and passed on to other neurons.
It's the kind of speculation that characterizes memory research.
Everything's pretty much up in the air, though the researchers themselves
carry on like all the basics are worked out, and it's just a matter of
filling in the gaps now.
