I’ve just discovered Brain Mart, an online shop for everything (and I mean everything) brain-related. They sell a great deal of educational material as well as a range of ‘brain novelties’.
These stretch from the classic (a phrenonology bust) to the anatomically correct ‘brain cap’ (“Flip up the brim and expose the words, Think, think, think…”) to the slightly worrying ‘Brain Charms’, for adding to a necklace or bracelet.
