Hi Stathis Papaioannou 

I don't think so, because the robot rat seems to keep running into things.
A real rat would skidaddle out of there.

 Hi Stathis Papaioannou

 It would be useful if the ratbrain robot scientists would
 try to do some kind of biological imaging (magnetic resonance ? who knows ?)
 to verify that the segment of rat brain isn't just acting as
 an electrical conductor (or resistor or capacitor or inductor).

 Maybe they could just mo9nitor some of those functions during its
 operations.

Neurons have resistance and capacitance, and if you changed these
variables the neurons would malfunction. But the question was about
the behaviour of the rat: do you think the robot rat could behave just
like a biological rat given a certain environment or not?

This experiment is not quite what you think.  It used only 60,000 rat
neurons (equivalent to the brain of a fruit fly), whereas a whole rat brain
has 1,000,000.  Also, it interacts with the chip through a small number of
electrodes (I think as few as 60, but it could be more).

That it runs into things could also be a consequence of limited sensory
data and/or poor motor control.
