#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

Save 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!

What can you discover with one powerful, streamlined pipeline for 3D #SpatialBiology? 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)

I am so proud to announce that I successfully defended my PhD yesterday in front of all the amazing exam members, family and lab family! Being the 1st PhD in the lab wasn't easy but so rewarding! Thank you @katrinachoe.bsky.social for making me love oxytocin so much and for believing in me🥂🥳

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!

Fantastic weekend at the Hypothalamic Mechanisms Retreat organized by @katrinachoe.bsky.social & Mijail Rojas-Carvajal ! Unfortunately didnt take too many pictures apart from the 'family tree' but it was so nice to share lots of unpublished work and get some critical feedback!

#eNeuro: Using fiber photometry in mice, @katycelina.bsky.social‬, Rychlik, and @katrinachoe.bsky.social‬ show oxytocin neurons and astrocytes respond to social and stress cues differently depending on the situation and sex of the animal. @mcmastermedia.bsky.social‬ vist.ly/3n7y6tc

Call for an Assistant / Associate Prof. just opened at the @crchum.bsky.social in the Neuroscience Axis ! www.chumontreal.qc.ca/en/emplois/a...

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! 👏🥰

🧪 The Sjöström Lab in Montreal is looking for a postdoc! We study cortical circuits, synaptic plasticity, and NMDAR signalling using custom 2-photon microscopy and optogenetics. We seek candidates with strong patch-clamp and/or 2-photon imaging expertise, and a relevant publication track record.

I have an opening in my lab for a postdoctoral fellow to work on projects that relate to the mechanisms of neurotransmitter release by dopamine neurons and/or on how inflammatory signals infuence the functionning of these neurons. Please share.

Fun times at #SOBP2025 with @gisellavetere.bsky.social @franklandlab.bsky.social Sheena Josselyn, Satoshi Kida, and Jessie Muir

Congrats to Sam Mestern, Ph.D. student at @westernu.bsky.social, for winning the MapMySpikes challenge! His tool, PatchOTDA, excelled in mapping electrophysiological data to molecular properties. 🧠📈 More on his tool and the MapMySpikes challenge: alleninstitute.org/news/canadia...

Important to understand that there is diversity in terminology preferences among people in the autism spectrum. though a majority of people prefer identity-first language (eg ‘autistic’), a significant minority prefer person-first language (eg ‘has autism). So it’s good to ask! #ACNP2024

Dr. Gillespie-Lynch unpacking the hidden curriculum is a key way to support neurodivergent folks #acnp2024

Coming soon: We have a Scientist position in the Neuroscience & Mental Health Program at SickKids. Should post details later this week. Stay tuned.

Tidbit from the #ACNP2024 women's luncheon: To be an effective leader, you need to develop the skill of having difficult conversations. This is done through practice.
