Sample data from an individual subject (#1) during a block of trials in which there was rotatory visual motion and a rotatory inertial stimulus.

<p>The circles in panels A&B represents the test stimuli given at a peak velocity with the diameter of the dot proportional to the number of responses at that stimulus level (the smallest dots represent a single stimulus and the largest 10 stimuli). The best fit cumulative distribution function (CDF) to the data is shown for each visual stimulus direction. (A) Responses to stimuli in which the visual stimulus moved to the right (implying leftward rotation in a fixed environment). (B) Responses to stimuli in which the visual stimulus moved left. The stimuli in panels A&B were randomly interleaved during the block of trials. (C) The CDF was fit to the data in A & B after being randomly resampled 2,000x. The mean was calculated for each iteration. The histograms of these means demonstrate no overlap between the two distributions.
