Walk from home to food source.
A. As there is no food, the agent performs a short cut to food source B. After having found food, it returns to home using one route landmark. As the local vector to the next route landmark is too short, path integration takes over. The catchment areas of the landmark elements home, and the two food sources A and B are shown by circles coloured in yellow and green, respectively. Catchment areas of route landmarks are shown in red or blue for outbound and inbound landmarks, respectively. Outbound walk is depicted by red squares, inbound walk by blue squares.
