Dr. Penninger possessed a large suite of laboratory offices within a brightly lit warren known as Neurocomputational Studies. A plastic door identified her as GRETA v. PENNINGER , PRINCIPAL INVESTIGATOR , and behind that door was a brightly lit surgical theater. Yards of white tabletop. Safety treading. Drying racks. Safety film. Detergents. Balances, fume hoods, graduated beakers. Hand pipettes. Centrifuges. Chromatographs. And a great many square white devices of utterly unknown function.
