A very cool-sounding word. Part of me wonders if we really need a "term" for this, but maybe we do.
"Further, in brain scan investigations, individuals who professed to be ‘truly, deeply and madly’ in love showed activity in several structures in common with in the neuroanatomy of OCD, for example the anterior cingulate cortex and caudate nucleus."
I wonder what these "structures" pertain to, as far as OCD goes.
Oh, and another good word is "propinquity." It's just so perky-sounding.
"Nothing propinques like propinquity, Mondale would say after a few weeks in his new office...."
