- Reposted by Katrina Choe#ThisWeekInNPP This study reports that manipulating oxytocin synthesis in anterior vs posterior paraventricular hypothalamic neurons produced opposing effects on social approach, while electrophysiological differences revealed functional heterogeneity
- Reposted by Katrina ChoeSave the date for the annual "Neural Circuits and Behaviour" satellite conference at the Canadian Association for Neuroscience annual meeting, cohosted by @franklandlab.bsky.social and myself on May 18, 2026. We have a great speaker lineup and will be selecting 4 trainees talks from our registrants!

Researchers in @katrinachoe.bsky.social's lab used whole-brain labeling, clearing, imaging, and ML-based cell detection to quantify OXT+ neurons across part of the hypothalamus called the PVN 🧵 (1/4)

- Yesterday marked a huge milestone for our lab - our first PhD defense ever, and a successful one! Couldn’t be prouder of Dr. Sandoval. Congratulations @katycelina.bsky.social 🎉 🥳
- Heading to San Diego to attend #SfN25! Excited to witness some jaw-dropping neuroscience 😲 Reach out if you’ll be there, would love to say hi!
- Thanks for your visit, awesome talk as always! @drjkhokhar.bsky.social
- Can’t wait for @drjkhokhar.bsky.social’s visit tomorrow! Don’t miss his talk at 2:30pm, PC 155!
- Super excited to be visiting @mcmasteruniversity.bsky.social tomorrow for my talk titled: How High? Impact of Cannabis Vaping, Edibles and Genetics on the Brain”! Thanks to @katrinachoe.bsky.social for the invite! Come by if you’re nearby!

- I am delighted to share a new review article from Aishwarya Patwardhan and me, titled "The Social Salience Network Hypothesis of Autism: Disrupted Network Activity, Oxytocin Signaling, and Implications for Social Symptoms" published in Progress in Neurobiology! doi.org/10.1016/j.pn...
- Thrilled to share that our paper is published! With this study, we reveal calcium dynamics of PVN oxytocin neurons and astrocytes in mice during social investigation and looming shadow threat, simultaneously imaged in vivo using two-colour fiber photometry. 🐭 🧠 🟢 🔴 www.eneuro.org/content/12/5...
- Jam-packed past few weeks celebrating @katycelina.bsky.social’s paper acceptance, a new paper submission, hosting Dr. Toru Takumi, and attending #SOBP2025 in Toronto with @neuroash.bsky.social @siyaoneuro.bsky.social and #SONA2025 at @westernu.bsky.social with (almost) the whole lab crew! 🥳🍾🤩
- So proud of you! 👏🥰
