Figure 5.

Comparison between visual and vestibular DI measured in the same neurons. A, Visual DI plotted against vestibular DI for all neurons with significant tuning in both conditions (n = 66). Shapes are as in Figure 4 C, and the diagonal is the unity slope line through (0,0). B, Histogram of the difference between the preferred heading in the visual and vestibular conditions. Cells with visual and vestibular heading preferences within 60° of each other were classified as congruent (A, filled black symbols; n = 35), cells with a difference >120° were classified as opposite (open symbols; n = 23), and the remainder were unclassified (filled gray symbols; n = 8).
