Correlation coefficients between duration of allogrooming and percentages of c‐Fos‐positive oxytocin receptor‐expressing neurones in oxytocin receptor‐Venus knock‐in heterozygous female mice. There were significant correlations between duration of allogrooming and percentages of c‐Fos‐positive oxytocin receptor‐expressing neurones in the anterior olfactory nucleus, insular cortex, lateral septum and medial amygdala but not in the cingulate cortex. The numbers of animals in the groups for non‐distressed control cage mates and for distressed cage mates were 7 or 9 and 8‐11, respectively. Data were analysed by Spearman’s correlation
