Fig. 6.

Time dependence of neuronal thresholds (A) and CPs (B). Gray lines represent individual cells (threshold: n = 62, CP: n = 54). Open symbols (○) and the thick black line illustrate population means. Each point represents data computed in a 400-ms analysis window that is shifted by steps of 50 ms. The vertical dashed lines represent the time of peak stimulus acceleration (time point used for all other analyses). Filled symbols (●) indicate that the mean CP is significantly different from 0.5 (t test: P < 0.05).
