I feel honored for the opportunity to present our recent work on the role of serotonin in regulating ultrasonic vocalizations in mice and rats across development at the 4th Ultrasonic Vocalization Conference tomorrow (online): ultrasonicvocalizations.net

Main Page - Ultrasonic Vocalization Network

The 4th Conference on Ultrasonic Vocalization (USV) will be held in Nov 2025 - a key event for scientists exploring USVs, rodent communication, behavior, and neuroscience.

As a longtime fan of cool papers in @currentbiology.bsky.social, I am really thrilled to see this out! This study sets the stage for understanding the origins of novel (vocal) behaviors. Big shout out to the main architects of this work @xmikezheng20.bsky.social and @cliffscience.bsky.social

In mice, rats, and monkeys, a lack of serotonin in the brain leads to impaired maternal affiliation. @tianhuawang.bsky.social now showed that early social enrichment has ameliorating effects but leaves prominent reduction in pup ultrasonic calling untouched. rdcu.be/eJjtX & doi.org/10.1016/j.pn...

🐀 ultrasonic vocalizations be wildin' 🐀 @nicolasmathevon.bsky.social etc al. use @openacousticdevices.info to study how striped mice use USVs in the wild, new in @currentbiology.bsky.social See graphical abstract for summary of results (does the work for us 😇) 👇 #bioacoustics #prattle 💬

Graphical abstract from paper in quoted post

Top panel depicts modulation of vocal repertoire use depending on territorial location

Next panel depicts group& specific information embedded in ultrasonic vocalizations

Bottom panel shows that individuals use this information to adapt their behavioral and vocal response. No behavioral change to groupmate playback, increased vigilance and vocal response to neighbor playback, and in addition to increased vigilance/response, retreat to nest in response to stranger playback

Can we study placebo effects in rodents? At the @sipsplacebo.bsky.social‬ 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 great round table discussions, ‪@sfb-trr-289.bsky.social‬!

Next we looked at vocalizations w/ 6,000 hrs of RFID box audio (thanks @openacousticdevices.info!) + ML to find vocal events Takeaways: 1. Vocalization is seasonal: most in spring/summer when social groups are small 2. Wild mice use both audible squeaks & ultrasonic calls, often close together 4/8

(Top) Percentage of recorded minutes with at least one squeak versus recording start date (mmdd). ANOVA: percentage of minutes with squeak ~ season, p < 0.001. Letters indicate seasons that differ significantly by Tukey post hoc test (p < 0.05). (Bottom) Percentage of minutes with at least one USV versus recording start date. ANOVA: percentage of minutes with USV ~ season, p < 0.001. Letters indicate seasons that differ significantly by Tukey post hoc test (p < 0.05)

Very happy to share the latest from my postdoc‬! 10 yrs of mouse social networks + 1.25 yrs of acoustic data ➡️ insight into vocalization & sociality in a wild population of your favorite lab model 🐁 paper: bit.ly/4n93yyD data: bit.ly/4lfFBEk code: bit.ly/4kNnMwx #bioacoustics #neuroskyence 1/8

Graphical abstract for "Vocal communication is seasonal in social groups of wild, free-living house mice."

The abstract has, from top to bottom, a title, four middle image panels, and two bottom text panels.

Image title: "Vocal communication in social groups of wild-free living house mice"

Middle image panels from left to right: (1) An aerial snap shot of the region where the study site is located, an agricultural landscape in rural Switzerland. (2) An image of the study site, a small barn in the forest inhabited by mice. (3) An image of a radio frequency identification (RFID) box used to track mouse social interactions. A mouse is entering the box from the left while another sits outside. (4) A spectrogram showing example vocalizations - one low frequency squeak and one ultrasonic call - recorded from an RFID box.

Bottom panels:
Left: Data Collection
- 10 years of RFID-based tracking data (from 6,946 mice)
- 15 months of acoustic monitoring (totaling 6,594 hours)
- Machine learning for vocal detection and labeling (CNN)

Right: Key Findings
- Vocalization is seasonal (most in spring and summer)
- Vocalization is associated with the presence of pups
- Vocalization is correlated with social group dynamics

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

It's hard to interpret observations like this because in the field we cannot control environmental factors that might be causing movement. Instead, we built 3D reconstructions of the environment using gaussian splatting with the goal of building causal models that can link environment + behavior.

We noticed periods of coordinated collective movement where some, but not all, animals appeared to participate. We implemented multi-animal tracking and a size-estimation model to show that larger rats move faster and are more likely to participate in collective bursts than smaller animals.
