A–F
, Summary of neural response amplitude and phase during tilt (
A
,
D
), tilt-translation (
B
,
E
), and tilt+translation (
C
,
F
), plotted as a function of the corresponding responses during translation. Each data point corresponds to an MSTd cell (n = 68), whose responses are shown either for lateral translation/roll tilt (squares) or forward/backward translation/pitch tilt (circles), whichever gave the largest modulation during translation (similar results were also seen when comparisons were made along the preferred direction). Filled symbols, Convergent neurons; open symbols, nonconvergent neurons. Solid red and dashed blue lines illustrate the predictions if cells selectively code for translation versus net linear acceleration, respectively. These are typically zero-slope or unity-slope lines, with two exemptions: slope-of-2 line (net acceleration prediction for tilt+translation amplitude) and 180°-difference diagonal lines (translation prediction for tilt+translation phase).
