Figure 2.

Sample behavioral and neuronal responses to rotational motion during two behavioral states: default state (left column) and simulated flight (right column). All data were recorded during y-axis (pitch) rotation (0.5 Hz, 20°/s). Representative EM (head-fixed), air-on (head-fixed), and NEM (head-free) neuronal responses are shown in the top, second, and third row panels, respectively. Stimulus angular velocity (S_PITCH), head-on-body velocity (H_PITCH), and tail-on-body velocity (T_PITCH) are shown in the bottom three panels and were recorded simultaneously with the NEM cell under head-free conditions. Neural waveforms are shown in gray, and corresponding IFRs are overlaid as black dots.
