Serotonin and motherhood: From molecules to mood.

Pawluski JL, Li M, Lonstein JS (2019) Serotonin and motherhood: From molecules to mood. Front Neuroendocrinol 53:100742. doi: 10.1016/j.yfrne.2019.03.001

Summary: Serotonin may affect how mothers perceive or behaviorally readjust to changes in the sensory cues emitted by their offspring as they age. The DR serotonin-lesioned mothers studied by Holschbach and colleagues (2018) were much less maternally aggressive, which was concomitant with reduced serotonin-immunoreactive fiber density in the anterior hypothalamus, a brain site previously implicated in serotonin’s influence on aggressive behaviors in male animals.
