Hmm, I thought I had some references handy here, since I attended a
seminar on this subject at Stockholm University a coupe of weeks
back. I seem to have misplaced my notes somewhere, but I recall that
the study they reviewed involved immune-linked genes. I'll get back on
this.

If you have a good health (or just the right kind of health that
leaves your brain functional even if your body is sick), the brain
might get more nutrients and be able to develop better. But there
might be other factors too, a wild hypothesis might be that some of
these genes create very useful wiring structures that others lack or
have to build by experience.
