Mark--Not really. But you should do some reading if you really want to
pursue this. Pribram's (1971) book would be a good place to start, though
it's probably out of print. The notion has been explored by Christopher
Longuet-Higgins and his collection of essays, _Mental Processes: Studies in
Cognitive Science_ (MIT 1987) has several articles on the subject; it is
still available. As you may know, there is quite a bit of research on
using holographic technology for computer memory; you might what to check
that out--see two articles by Psaltis below.

One thing that makes neural holography so attractive is that holographic
memories can be made content-addressable, thereby taking care of items 2,3,
and 4 on your list. In the brain the cerebral cortex is the memory medium.
The cortex is parcelled into a number of neurofunctional areas (such as
Broca's area), each having unique patterns of input and output. Input
comes into a cortical NFA in parallel and is, for all practical purposes,
presented to all processing units (columns of 80-100 neurons perpendicular
to the cortical surface) in parallel. The NFA as a whole outputs the
stored pattern which most closely matches the input pattern. assuming that
there is one that is within tolerance. If there is not stored pattern that
is a close match, then the current input pattern is learned as a new
