Thanks for the highlight!.
#eNeuro: Using fiber photometry in mice, @katycelina_, Rychlik, and Choe show oxytocin neurons and astrocytes respond to social and stress cues differently depending on the situation and sex of the animal. @McMasterU.

Hi 👋 I am Katrina Choe, an assistant professor at @McMasterU and a first time attendee at #ACNP2024! My lab studies effects of autism-linked genes on neural mechanisms underlying sociability. Day 1 and already ran into so many familiar faces, I think I’ll fit right in! 😎.
We are officially on the ground in Phoenix so it's time for the #ACNP2024 role call 📣. Introduce yourself, your science, tell us if you're a veteran or first-timer, promote your poster/talk/favorite social - whatever you want, this is your space to say it ⬇️
