Figure 8.

Responses to sideways direction inversion during forward flight. This figure shows the vCH responses to translational direction changes. The color code is as in Figure 5 (Eristalis vCH n = 8 | Calliphora vCH n = 5). Plots show mean responses (±SD) of Eristalis and Calliphora vCH cells, respectively, in a 44-ms time window centered about the movement direction switch from forward-right to forward-left (A,B) or vice versa (C,D) (see insets). At 0 ms the direction switches. Responses in (A,C) were elicited by Eristalis flights. The stimuli in (B,D) were from Calliphora. The time shift denotes the time difference between reaching the half-maximal response in Eristalis and Calliphora vCH, respectively. Resting potential is marked by the dashed black line. Note the differently scaled y-axis in (D).
