I am going to be responsible for two posts to the list today! I thought we
ought to get some discussion going on what people have posted so far, so
have put a couple of "discussion questions" for people below...

Tony, to what extent do you think this co-opting occurs? Of course, it is
also argued that there is an innate domain-specific numerical cognition
ability... do you think that this could also be the case, but that it might
be only responsible for some aspects of processing, and that domain general
co-opting could be responsible for the remaining processing? Or are you
arguing that all of numerical cognition is founded on domain general
abilities? (At the risk of starting a controversial debate here!!)

Ed, have you done any experiments to try and test this hypothesis directly?
I'm not quite sure how it could be done, but for instance, what about
looking at concurrent activation of adjacent areas in these patients in an
event related fMRI design - it would be neat if it could be shown that the
"higher" synesthetes show a bigger correlation between HIPS/spatial area
activation, whereas the "lower" synesthetes show a bigger correlation
between fusiform/color areas. This might be hard though... I guess one
would have to functionally identify all the areas involved.
OK, back to the dissertation grind...
