Oxytocin isn’t just the “love hormone”: it helps wire the brain’s metabolic circuits! 🧠
In our new @plosbiology.org study, we show that OT neurons guide the postnatal development of POMC and AgRP pathways that control energy balance

Oxytocin neurons drive melanocortin circuit maturation via vesicle release during a neonatal critical period
The melanocortin circuit of the hypothalamus is crucial for regulating energy balance, but the development of this circuit is incompletely understood. This study in mice shows that activity and vesicl...

A striking white coloration makes this spiny skate (Bathyraja spinosissima) easy to spot. These active swimmers hover and glide well above the seafloor, while their relatives tend to stay close to the bottom. This species is especially common in rocky lava fields.

Delighted to see this finally out: rdcu.be/eO9oW
We tested whether brief striatal dopamine release events influence the vigor of skilled movements. Despite popular belief, we did not find any evidence linking rapid dopamine dynamics to motor vigor on a moment-by-moment basis.

Conrad Hal Waddington was born OTD in 1905.
His “epigenetic landscape” is a diagrammatic representation of the constraints influencing embryonic development.
On his 50th birthday, his colleagues gave him a pinball machine on the model of the epigenetic landscape.

New article from the lab out today, in which we discuss how social behavior evolves at the molecular level. From parenting across the animal tree of life to caste systems in social insects, it’s all connected (and, therefore, slowly starts to make sense)…
Parental care, and more complex cooperative systems of care, have independently evolved in hundreds of animal lineages. In an article published today, we explore how these behaviors evolve 𝘢𝘵 𝘢 𝘮𝘰𝘭𝘦𝘤𝘶𝘭𝘢𝘳 𝘭𝘦𝘷𝘦𝘭l shorturl.at/g5OPw /1
