Reply: An interesting idea, though I worry a considerable amount about
validity of data in a database when the conditions of recording are
unknown. So the evolution of this database is unclear to me at this point.
On the other hand, certainly an interest group might draw together
collaborators who were otherwise unaware of each other. So I suggest
that the initial database should be investigators and their interests, and
whether they want data or can supply it, or both.
Perhaps each registrant could list keywords that could be used in a
quick database search. Each registrant might download the whole database
at intervals, for search using whatever tools they have. This would
simplify the database.
Any comments as to where a bulletin-board interchange might be located?
Are you proposing to have this feature also?
Here at Abratech we are working on dipole models of evoked potentials,
especially the Auditory Brainstem Response. Early and middle somatosensory
responses are also of interest. We are also interested in multishell
models and head shape models (boundary or finite element). We can
generate up to 32 channels of scalp data in humans.
I'll supply more info if this gets moving.
