Fig. 7. Variability of the anterior extreme position (AEP) and posterior extreme position (PEP) during inside stepping in the middle leg. (A–C) Intact animal, (D–F) 2L-preparation and (G–I) 1L-preparation. A,D,G: Scatter plots of the AEP and PEP of the middle inside leg in the intact, the 2L- and the 1L-preparation. B,C,E,F,H,I: Histograms of the frequency of the occurrence of AEP and PEP x- (B,E,H) and y-positions (C,F,I) in the inside middle leg of the intact animal, the 2L-preparation and the 1L-preparation. AEP in green; PEP in orange. All positions are given in mm.
