Well, I WILL ask: what is Bauplane?  German for "building plan"?

re vertebrate and arthopod inversion: yes, we (speaking for myself,
anyway, as a vertebrate) have skeletons on the inside, and "they" have
skeletons on the outside; but do you have in mind something more
profound than that?

And yes, there do seem to be common mechanisms involved in brain
plasticity at the level of memory formation and at the level of
