Fig. 3. Odor does not alter the magnitude or time course of steady-state collision
avoidance reflexes in closed-loop conditions. Flies were presented with a
2.5-s bias in expansion, with and without concomitant presentation of 30-s
odor pulses. Each trace represents a time series average. Each fly received
three visual trials within each of nine consecutive odor trials (N=16
flies).
