Exciting new paper on the role of serotonin availability in our ability to learn about social ranks. Lower serotonin levels in a critical brain region (dorsal raphe nucleus) were better for learning about social hierarchies (social dominance). This link was specific for social learning contexts, as shown in a non-social control task. Learning about one’s status in a group is fundamental to building social hierarchies. Congrats to Remi’s new insights into the neurobiological basis of this critical human ability! You can find the full paper here: https://www.nature.com/articles/s41386-022-01378-2
