The relative contribution/weighting of individual stimuli for the neuronal responses depends on the driving strategy. (A) Three-dimensional scatter plot of the responses to optic flow alone, object motion alone, and the drive by optic flow, matched heading condition. A multiple linear regression indicated a strong correlation (r² = 0.96) with a large significant beta weight for optic flow (0.92) and small nonsignificant beta weight for object motion (0.07). (B) Three-dimensional scatter plot of the responses to optic flow alone, object motion alone, and the drive by matched heading object motion condition. A multiple linear regression indicated a strong correlation (r² = 0.95) with a small nonsignificant beta weight for optic flow (−0.06) and a large significant beta weight for object motion (0.98). Thus, in identical matched heading stimulus conditions, the weighting for the cued driving stimulus increases while the irrelevant stimulus decreases.
