What is it about?
Reciprocal altruism is one mechanism by which cooperation can evolve among animals; in this case, animals cooperate because it is more likely that other individuals cooperate with them in the future. How does this happen in the brain? This paper examines the role of the neurotransmitter serotonin in conditional approach in guppies, a model organism in behavioral ecology.

Why is it important?
Our findings show that cooperation is accompanied by fear in this model, and that serotonin increases cooperation even as it increases fear of a potential threat. Thus, the neural circuits that control the social strategies of vertebrates are shared with the circuits that control fear.
