Note: Sample sizes vary because some individuals were excluded from data analysis due to poor tissue quality.
indicates that 1-day and 14-day dominants significantly differed from 1-day and 14-day subordinates, respectively (p < .05).
indicates that animals paired for 14 days significantly differed from animals paired for 1 or 7 days (p < .05).
indicates a significant difference compared to corresponding handled controls (p < .05). BLA – basolateral amygdala, dLS – dorsal lateral septum, vLS – ventral lateral septum, MPOA – medial preoptic area, PVN – paraventricular nucleus of the hypothalamus.
