1. Effects of arginine vasotocin (AVT) on the production of type-I chirps by a single male.
Effects of arginine vasotocin (AVT) on the production of type-I chirps by a single male. (A) Counts of type-I chirps per stimulus presentation during control conditions, following saline injection and following 0.04 (filled symbols) and 0.08μgg−1 (open symbols) doses of AVT. Asterisks indicate chirp counts from the recordings of Fig.5A,B. (B) Type-I chirp counts from the −4Hz difference frequency (DF) stimulus presentations interleaved with the −12Hz DF stimuli. (C) Histograms summarizing the mean numbers of type-I chirps evoked by −12Hz DF stimulation during the six control stimuli (light gray columns), during the six stimuli following saline injection (dark gray columns) and during nine stimuli following the indicated AVT doses (black columns). Values are means ± s.e.m.
