New team member! Very happy to welcome Henry Werk who is joining the @Wohrlab @Uni_MR site. He will study the effects of lithium in a rat model for mania, integrating brain and behavior through recording 50-kHz ultrasonic vocalizations. Looking forward to exciting science.

@fabdechaumont et al. showcase how the integration of ultrasound recording and behavioral analysis can provide novel insight into mouse social behavior, linking ultrasonic calling to urination behavior. Another great contribution to our special issue: sciencedirect.com/special-issue/…

New in @ScienceMagazine! 🎉 Thrilled to share my PhD project, we introduce a new optogenetic approach to study the developing brain - revealing how oxytocin shapes infant behavior. Thanks to my collaborators, @OferYizhar & my family❤️ science.org/doi/10.1126/sc… Here’s the story🧵

@ScienceMagazine @OferYizhar Oxytocin is famous for shaping adult bonding. But in early life, its role was unclear. We noticed oxytocin receptors strongly expressed in infancy, in both humans and mice - yet their function was unknown. We asked: how oxytocin influences pups’ cries during separation & reunion?

@ScienceMagazine @OferYizhar Studying the infant brain is tough. To overcome this, we combined behavior, fiber photometry, and pharmacology with a new wireless, noninvasive optogenetic method. This let us monitor & manipulate oxytocin neurons in freely behaving pups 🐭💡

@ScienceMagazine @OferYizhar We found that oxytocin neurons became more active during separation, and this activity was tightly linked to pups’ calls. Blocking or silencing oxytocin changed calling - not only during separation but also at reunion with the mother.

@ScienceMagazine @OferYizhar Together, these findings reveal oxytocin’s crucial role in shaping early-life bonding, and our new tool opens opportunities to explore the developing brain 🧠 This was a long journey and a true team effort!❤️ Huge thanks also to Shari Ross for her beautiful drawings!

Finally, we used a wireless ultrasonic mic to record vocalizations. We observed a diversity of calls which have acoustic features that lay outside of the std distribution reported in the lab. We see interesting usage of the classically negative affect 22 kHz call during foraging.

Thermal imaging worked great at our sites. High SNR and able to see through vegetation in parks.

We mined NYC311 reports of rat sightings to pick a time and place to perform the field studies. We settled on 3 recording locations in distinct environments (subway, park, sidewalk): Union Square Station, Central Park (Ramble), and W 125th St.

New preprint! tl;dr — We ran around late at night to record wild rats in NYC and figured out how to quantify their behavior and environment. 🧵 w/ Dima Batenkov, @zamakany, @e_mackevicius biorxiv.org/content/10.110…

Can we study placebo effects in rodents? At the @SIPSplacebo ECR Summer School in Kraków, Poland, I was proposing that we can do so by using ultrasonic vocalizations as a key element of the anticipatory response. Thanks for the stimulating round table discussions, @sfb_trr289!
