Quark's

I understand why they're so heavily invested in a neurological model for this, but it's a little surprising that they don't appear to have any behaviourists involved (at least, not from the way the journal article is written). They would have a lot to offer in terms of the nature schedule and of the "feedback" provided.

I missed the earlier story but apparently they taught these things how to play Pong, then started working on teaching them how to play Doom!
