Goodson and colleagues (2005) hypothesized that the pattern of activity across the brain regions forming the social behavior network would vary in species of birds that differ in the typical size of their social group. When two species of waxbills were exposed to a same-sex conspecific, activity in the brain regions involved in social stress and dominance related behaviors A) failed to support Goodson's hypothesis. B) was higher in the territorial waxbill species than in the more gregarious waxbill species. C) was lower in the territorial waxbill species than in the more gregarious waxbill species. D) was surprisingly unaffected by the social interaction.

Question

Goodson and colleagues' hypothesis was supported by finding that activity in brain regions involved in social stress and dominance behaviors was higher in the territorial waxbill species compared to the more gregariously social waxbill species when exposed to a same-sex conspecific. This suggests that the pattern of brain activity varies with the typical size of the social group, with more solitary or territorial species showing greater neural response in these contexts.
