#1 I'm guessing is that our goal-directed task was rather weak providing little modulation. Rats certainly learned the transition structure, but I think very self motivated by exploration, rather than reward prediction.
Definitely one reason I think. Also, the scale matters a lot in our data: similarity of movement within compartment on a few centimeter- and 1 sec scale matched CA1 but not transitions between compartments. Also, behavior during early experience, not after familiarization, was strongest.
