Responses after a step back to horizontal from an eccentric angle are strongly correlated with activity before the step. A, Schematic of stimuli used to compare responses after return to horizontal (black) to responses at the eccentric angle (magenta). Solid lines indicate stimulus periods where neurons are in focus, and dashed lines indicate stimulus periods where neurons are out of focus. B, Concatenated traces of mean normalized fluorescence responses (± SD) before, during, and after a ipsilateral roll step of 30° for two example neurons with differing response temporal dynamics (fast decay on left, slow decay on right). C, The mean fluorescence during the last second of the eccentric step is strongly correlated with the mean fluorescence during the first second on return to horizontal for all neurons (n = 26 neurons; ρ = 0.94). Example fast- and slow-decay neurons in B identified with a star and square. D, Distribution of calcium response decay slopes during the eccentric step for all neurons. E, Distribution of times-to-peak normalized fluorescence during the eccentric step for all neurons.
