Figure 7.

Familiar odor cues alone failed to elicit stable fields or effectively guide field rotations. Fields in the absence of visual cues were typically only poorly defined and did not correlate well across the 6-h delay. This was true both in the presence (A) and absence (B) of stable odor cues. The number of cells that did achieve the minimum correlation of r >.03 was insufficient for an analysis of distributions of best-fit angles of rotation. However, visual inspection of the distribution clearly indicates that rotations were largely random both with stable odor cues (C) and without such cues (D).
