Figure 3. Differences in the ultrasound vocalization of NL-3 and NL-4 KO mice.

Figure 3

(a) Differences in number of calls and latency to call of male mice courtship vocalizations (N: NL-3WT = 25; KO = 5; NL-4WT = 20; KO = 16). Figure compiled from data presented in (Jamain et al. 2008; Radyushkin et al. 2009). (b) Frequency spectrogram demonstrating the possibility to produce similar call types, WT = wild-type male, KO = NL-4KO male.
