German to English Science Science (general)

I could be sure that there is an English equivalent for this word that is more appropriate than a literal translation of “think cells”. I think I have been living outside of the English-speaking world for too long now and I can’t seem to come up with it! Also, if anyone has any suggestions about the wording of the rest of sentence, I would be happy to hear them….it reads terribly at present but I couldn’t seem to come up with anything better just yet.

“Der Bau folgt seiner Funktion als Physik-Institut mit den drei Hauptbereichen, die in jedem Geschoss vorkommen: Labore für die experimentellen Physiker, graue "Denkzellen" für die theoretischen Physiker sowie jede Menge Haus- und Forschungstechnik.“

My translation so far:
„The building functions as an institute for physics with the three main sectors that can be found on every floor: laboratories for experimental physicists, grey “thinking cells” for theoretical physicists as well as a significant amount of building services and research technologies.”

Thanks a lot!
