Fig. 4. During the duration of an odor pulse, motor responses to visual and
olfactory cues represent the linear superposition of responses to each
stimulus presented alone. Data sets are segregated into responses to visual
bias during control water vapor delivery (i; Rv), odor in
the absence of visual bias (ii; Ro), both stimuli
simultaneously (Rv+o; indicated by black lines, iii), and
the sum of responses to each stimulus presented alone (Rv
+ Ro; indicated by red lines, iii). N=22.
