Subjects were scanned while learning 2 pairs of overlapping routes on the NYU campus. Subjects completed 14 rounds of route learning during which they viewed repetitions of the routes and learned to predict the destination of each. To encourage learning catch trials were included during which the route would stop in the middle and subjects would be asked to either identify 1) the final destination of that route or 2) the direction of the next turn in the route (right/left). After exiting the scanner subjects completed a picture test in which they were shown still images selected from the routes and were asked to identify the destination associated with each image. Two independent experiments were performed using different sets of routes.
