Our study on the effects of running wheel access on female mouse social behaviors has been published! @cornellpsych.bsky.social journals.plos.org/plosone/arti... bsky.app/profile/kati...
journals.plos.org
Presence of a home cage running wheel, but not wheel running per se, decreases social motivation in adult C57BL/6J female mice
Physical activity offers myriad benefits to health and well-being, in humans and other animals as well. In rodents, voluntary wheel running can attenuate the effects of both physical and social stress...

It turns out that home cage running wheels impact the social behaviors of female mice, but not for the reasons we thought! Thanks to our reviewer for a great control experiment suggestion. Please RT! www.biorxiv.org/content/10.1... bsky.app/profile/kati...

Very excited to dig into the next steps and to continue learning more about RAm! The hindbrain is small but mighty (and complicated!)
010
Katie Tschida @katietschida.bsky.social · 19/03/2026
Surprisingly, these two vocalization types drive different patterns of RAm Fos expression. Our results are consistent with the idea that RAm is heterogeneous and may contain multiple populations of vocalization-related neurons (USV-only, squeak-only, and shared neurons important for both).
111
Katie Tschida @katietschida.bsky.social · 19/03/2026
In this study, we considered the nucleus retroambiguus, a hindbrain premotor region important for vocal production. We directly compared patterns of Fos expression in mice that produced USVs with mice that produced squeaks.

Katie Tschida @katietschida.bsky.social · 19/03/2026
Our lab has become really interested in understanding how brainstem circuits are organized to regulate the production of different vocalization types (i.e., mating calls, territorial calls, etc.).

Imagine, if you will, that NASA updated its website to suggest gravity might not exist, prompting CalTech and CERN to release statements saying, "With great sadness, we can no longer recommend listening to NASA." This is what's happening in epidemiology.

It’s widely known (and, I think, pretty uncontroversial) that learning requires effort — specifically, if you don’t have to work at getting the knowledge, it won’t stick. Even if an LLM could be trusted to give you correct information 100% of the time, it would be an inferior method of learning it.

Interestingly, there is past work showing that mice will forgo reinforcers (even cocaine and amphetamine) to gain access to a running wheel. So one possibilty is that running wheels are like crack for mice and decrease their sensitivity to other rewards, perhaps even social rewards.
171
Katie Tschida @katietschida.bsky.social · 29/09/2025
These effects on social behavior are somewhat long-lasting, as they're not reversed by a 2-week period with running wheels removed and replaced with a standard paper hut.
110
Katie Tschida @katietschida.bsky.social · 29/09/2025
Unexpectedly, we found that free access to running wheels in the home cage, either for 5-weeks over adolescence (weaning till adulthood) or even for a 2-week period in adulthood, inhibits social motivation in group-housed female mice when they are given the chance to interact with a novel female.

Katie Tschida @katietschida.bsky.social · 29/09/2025
New story to share! We routinely put running wheels in our mouse cages. The mice love them, and there's lots of evidence that exercise is great for health. Given our focus on social behaviors, though, we wondered whether running wheels change mouse social behavior. www.biorxiv.org/content/10.1...

I listened to Bhattacharya on Steve Bannon's "War Room" podcast. If you want to know how it went, see the following email that I just sent. 1/13
Dear Dr. Bhattacharya:

I have listened to your performance on the “War Room” podcast with Steve Bannon. The segment begins with a discussion of Secretary Kennedy’s recent cancellation of $500M worth of contracts related to mRNA vaccines.

You say “You can’t have a platform where such a large percentage of the population distrusts the platform as we use it for vaccines and expect it to work.”  Later, you make comments that might explain why a large segment of the percentage distrusts this platform. For example, you say that the vaccine was not protective against contracting COVID and cite your own case on COVID after being vaccinated. However, you fail to cite the evidence for the clinical trials that led to the Emergency Use Authorization.

These results set the stage for future work to investigate how changes in brain circuits important for vocalization enable the context-dependent regulation of vocal communication over development. Stay tuned!
