Biologically Plausible Dynamic Artificial Neural Networks

Because M.D. Ross was the first reference in the posting, and I work in her
lab at NASA Ames, I feel some need to post also. Dr. Ross is a neuroanatomist
and we study nerves in the vestibular macula at the ultrastructural level. 

First, I have never heard her refer to a DANN in the manner the post does, and in
the post she is referenced right after this acronym.

Second, with respect to Ulf's posting, we do use both artificial neural net
models as well as electrophysiological models here in the Biocomputation 
Center. There are some questions that are best answered with one of those models
because they are too hard to answer with the other type. We have far more time
in the 'real' models than the artificial, but some networking questions are
still best posed in the context of an artificial neural net just because of
the huge computational requirements for networks of more realistic nerves. We
are, however, scaling up our 'real' models to ask such questions. In those cases
we plan to burn several hundred hours of CRAY YMP time. Thank goodness (and the
US taxpayers) that NASA has the supercomputers.

These statements are mine, and not those of the Biocomputation Center

The thought police insist I tell you:
my thoughts, not NASA's
