Number of ultrasonic vocalizations and correlation between number of c-Fos-ir cells and number of 50-kHz calls. (A,B) Numbers of 50-kHz calls (A) and 22-kHz calls (B) during stroking stimuli before brain sampling. (C–J) Correlations between numbers of c-Fos-ir neurons in the primary somatosensory cortex (S1) (C), dorsolateral orbital cortex (DLO) (D), secondary somatosensory cortex (S2) (E), granular insular cortex (GI) (F), septhohypothalamic nucleus (SHy) (G), medial preoptic area (MPA)-anterior hypothalamic area (AHA)-lateroanterior hypothalamic area (LA) (H), medial amygdaloid nucleus anteroventral part (MeAV) (I), and medial amygdaloid nucleus anterodorsal part (MeAD) (J) and number of 50-kHz calls during stroking stimuli. In the SHy, MPA-AHA-LA, and MeAV, there were significant negative correlations. †, P < 0.01, *, P < 0.05. Spearman’s correlation test.
