Data Sheet 1_Behavior in asymmetric dominance pairings predicts physiology, neural response, and neurogenesis in a social cichlid fish.pdf

We then assessed the impacts of this dominance pairing on the brain, and found that individuals who displayed more dominance behavior had lower neural activity when assessed across three forebrain regions. Lastly, a single week of pairing was not sufficient to induce changes in neurogenesis, but individuals who displayed more dominance behavior showed lower levels of neurogenesis.</p>Discussion<p>Like adults, juvenile Astatotilapia burtoni form dominance relationships after only one week of cohabitation.

As the first to explore neurogenesis in juveniles of this species, we identified sites of particularly active neurogenesis and one region (the extended amygdala) as a potential novel site of juvenile-specific neurogenesis.</p>
