Fig. 8. Summary of the effects of arginine vasotocin (AVT) on male type-I and type-II chirp production in response to -12Hz difference frequency (DF) stimuli. (A) Mean type-II chirp production during control conditions, following saline injection and following AVT injection. (B) Mean type-I chirp production during control conditions, following saline injection and following AVT injection. Open symbols, mean responses of animals showing significant responses to AVT (mean chirp rate following AVT > mean rate following saline, P
0.05, t-tests). Filled symbols, mean responses of animals showing non-significant responses to AVT. (C) Mean magnitudes of the jamming avoidance response (JAR) during control conditions, following saline injection and following AVT injection. Open symbols indicate JAR responses of animals showing significant effects of AVT and filled symbols indicate JAR responses of animals showing non-significant effects of AVT injection. Values are means ± S.E.M. (N=12).
