Summary of heading tuning in response to inertial motion in the vestibular condition versus complete darkness. A, Distribution of the differences in preferred heading for 14 neurons tested under the standard vestibular condition, with a fixation target, and in complete darkness with no requirement to fixate. The difference in preferred heading was binned according to the cosine of the angle (in accordance with the spherical nature of the data) (Snyder, 1987). B, Scatter plot of HTI values for the same 14 cells tested under both conditions. C, Scatter plot of the maximum response amplitude (Rmax) under both conditions.
