The Habituation/Cross-Habituation Test Revisited: Guidance from Sniffing and Video Tracking

Figure 4

Proximity and velocity are correlated with S1 trial sniff rate in WT mice. On each trial (PE3, S3) for each WT mouse () the mouse nose proximity (Distance ) and head orientation (Angle ) to the odor source and the velocity of the mice were regressed onto the sniff rate. Distance was negatively correlated during S1 trials, whereas velocity consistently positively correlated with sniff rate. The relation with angle was inconsistent.
