🐟+🐚 =🏠 Shell-dwelling cichlids are true underwater architects, instinctively transforming empty snail shells into protective nests. New research shows: They improve with practice, remember what they learned, and adapt to unusual conditions. 🔗 Press release: www.bi.mpg.de/news/2026-04...

I defended my PhD 10 years ago today. That was the least remarkable thing that happened that day. Sharing something I wrote about it last year. Since then "the horrors persist but so do we." And with dignity.

Exciting new work by @merylneuro.bsky.social et al unpacking how sensory info from the heart impacts the processing of emotions in the brain, focused on one of the most mysterious and fascinating brain regions, Insula. #GoTeamInsula www.biorxiv.org/content/10.6...
Heartbeat tuning increased during both appetitive and aversive emotion states, a process not simply explained by increases in heart rate. Manipulation of sympathetic cardiac arousal using beta-adrenergic blockade disrupted neuronal encoding of emotion states in the pInsCtx and blunted behavioral and bodily emotion expression

1/8 New preprint alert! How are signals from the heart encoded in the brain? What could be the functional implications of cardioception? We found that neurons in the posterior insular cortex are precisely tuned to heartbeats, and that this cardio-insular coupling supports emotion coding in mice.

1/8. New preprint! Using fUSi in head-fixed mice🐭, we found that arousal events trigger a brain-wide wave of activity 🌊🧠. Surprisingly, this pattern was preserved during opto manipulations of the locus coeruleus, pointing to a minor role for noradrenergic tone. www.biorxiv.org/content/10.6...

Thrilled to share that our work is now published in Science! ✨ We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭 www.science.org/doi/10.1126/... 🧵1/

Are interoception and mental health linked? Many assume so, with interoception even described as a psychiatric “p-factor.” But in our latest preprint, we were surprised to find little evidence for such a connection. www.medrxiv.org/content/10.1... 🧵 Thread with our reflections on the matter 👇

A cross-species study captured an emotional brain state characterized by lingering brain activity in higher-order areas. “It’s one of those moments where you’re getting a first glimpse at a vast and complex landscape,” says @deisseroth.bsky.social. By @callimcflurry.bsky.social bit.ly/3U33raF

Eye puffs prompt separable sensory, affective brain responses in mice, people
Post-puff brain state might not be an emotion, some researchers caution, but the protocol provides a cross-species approach to study emotions.

Thanks @alexkwan.bsky.social! It was quite an effort indeed 😅 But I hope it'll be valuable for many labs studying effects of Psi on mouse behavior.
