- 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.

- my thoughts, not NASA's
