A few days ago I advertised a preprint entitled "Optimizing cortical
mappings" by Goodhill, Finch and Sejnowski. Unfortunately since then
the ftp and http details have changed. The new ones are
ftp://ftp.cnl.salk.edu/pub/geoff/goodhill_nips96.ps.Z
and
http://www.cnl.salk.edu/~geoff
Apologies,
Geoff Goodhill
