Fig. 5. Visual feedback alters the time course of the odor-off response. (A) Time series average of closed-loop control without either visual bias or odor. (B) Average odor responses without visual bias (black lines) decay along a slower time course compared with odor responses coupled with impulsive visual bias (red lines). N=22. R_b, response to baseline; R_oo, response to odor-off; R_oo+v, response to odor-off and visual bias.
