Supplementary Figure 5: Movement-related modulations in VS cells
From: A faithful internal representation of walking movements in the Drosophila visual system
(a) Vm of a VS1 cell triggered at the onset of postural adjustments in walking (left), or activity (right) bouts. n = number of bouts. Lighter traces show triggered data from individual bouts. (b) Left, the mean Vm of the population of VS cells (mean±SEM) triggered at the onset of walking (black) or activity (gray) bouts. Right, the mean Vm triggered at the offset of walking (black) or activity (gray) bouts. n = total number of bouts. For walking onset bouts, N=10 cells. For activity onset analysis, N=6 cells. For walking offset analysis, N=7 cells. For activity offset analysis, N=4 cells. (c) Distribution of the 10% rise time of the Vm (see Methods) relative to the onset of walking bouts. Arrowhead indicates the median value. (d) ΔVm (color-coded) as a function of the forward and angular velocities of each individual fly. (e) ΔVm (color-coded) is plotted as a function of the forward and angular velocities of the fly for the population of recorded VS cells, right and left cells were pooled together (see Methods). Scale bar is the same as for the maps in (d).
