ラットの超音波音声の多様性論文、出版されました！
なかなかいいタイトルでしょ？
Beyond dichotomy: Diversity of ultrasonic vocalizations in rats sciencedirect.com/science/ar…
もう言った気もするが、ラットの超音波音声の論文やってます（re-revise中）
ラットは長くて低い声（約22kHz）と短くて高い声（約50kHz）を出すと言われてきました。でも論文400本くらい調べてプロットすると、中間ぐらいのが結構あることが分かりました。おもろいぜ！

Our latest article investigated how the administration context influences the sensitization in the emission of 50-kHz ultrasonic vocalizations in amphetamine-treated rats.

In mice, rats, and monkeys, a lack of serotonin in the brain leads to impaired maternal affiliation behavior. @wang_tianhua now showed that early social enrichment has ameliorating effects but leaves the prominent reduction in pup ultrasonic calling untouched. Study links below.

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:

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❤️

Here’s the story🧵
Rodent Ultrasonic Vocalizations retweeted
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?

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 🐭💡

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.

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!

Separation-induced ultrasonic vocalizations in mouse pups are modulated by attachment and tightly linked to the activity of hypothalamic oxytocin neurons. New @ScienceMagazine study by Zelmanoff et al. from the @OferYizhar lab.

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.
