Whether AHV tuning depend on head motion or visual flow is area dependent
(A) Experimental configuration. (Left) Mouse is rotated 180° back and forth in CW and CCW directions and at different rotation speeds. (Middle) Same experiment repeated in the dark. (Right) Mouse is stationary, but now the wall of the arena with visual cues is rotated to simulate the visual flow experienced when the mouse is rotating.
(B) Percentage of angular velocity-tuned neurons mapped onto the mouse dorsal cortex, tested under each of the three conditions.
(C) Percentage angular velocity-tuned cells across different cortical areas (average ± SEM) tested under each of the three conditions.
(D) The decoding error (black, average ± SEM) and percentage of angular velocity-tuned cells (color coded) under the three different conditions. The horizontal bars above show the Mann-Whitney unpaired test p values. The dashed line shows the p = 0.05 level for the decoding error. The numbers of cells and mice recorded under light conditions are given in the legend of Figure 6. Under dark conditions, results were as follows: V1, 2,385 cells from 8 mice; V2, 4,564 cells from 10 mice; RSC, 4,963 cells from 10 mice; PPC, 1,044 cells from 4 mice; M1+M2, 2,489 cells from 7 mice; and S1: 3,398 cells from 9 mice. During wall rotations, results were as follows: V1, 1,864 cells from 6 mice; V2, 3,560 cells from 8 mice; RSC, 3,192 cells from 7 mice; PPC, 816 cells from 3 mice; M1+M2, 1,095 cells from 4 mice; and S1: 1,562 cells from 6 mice.
