Overall weighting of the input variables derived from the PCA for 3 subjects. The first 3 bars (blue) represent a subsequent non-overlapping 40 sec time period to sled motion only. The next 3 bars (red) represent non-overlapping 40 sec time periods to scene motion only. The last 6 bars represent non-overlapping 40 sec time periods to both sled (blue) and scene (red) motion. The direction of each bar indicates the relative phase between the response and the input signal.
