Figure 7.

A) Pool positions used during hidden platform training (positions 1–4) and the no-platform probe trial (positions 5–8) to compare place and directional navigation in Experiment 3. For all panels of this figure, the point marked by the open circle where the two lines cross was designated as the room origin. B) LEFT: The four pool positions and platform locations used during training for all rats in the Absolute condition. RIGHT: Pool position, release point, and analysis regions used during the probe trial for one rat from the Absolute condition. The black square and surrounding circle represent the target region and the open rectangle and surrounding circle represent the non-target region. Small black circles mark the training and probe release points for panels B and C. C) LEFT: The four pool positions used during training for all rats in the Relative condition. The platform locations shown here represent the locations used for the 2 animals trained with the platform in the north region of the pool. RIGHT: Pool position, release point, and analysis regions used during the probe trial for one rat from the Relative condition (north location).
