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...
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...
Funny to see my research subject being casually discussed in a vanity fair interview 😅 "your mind is like I could be nervous but I don't feel it so I won't be nervous" *Check in with your Dr. first* (important advice) www.instagram.com/reel/DSNlTvN...
VANITY FAIR on Instagram: "Did @treaclychild take a beta-blocker before this interview? VF asks @treaclychild, @jtfirstman, @odessaazion, @truewhitaker, and @jhutch1992 —the cast of ‘I Love LA’—the ...
From beta blockers to pre-interview jitters, the cast of 'I Love LA' gets real about their experience on the show. Watch now and see what they have to say about what really happens when the camera isn...

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 👇
Interoceptive Ability is Unrelated to Mental Health Symptoms: Evidence From a Large Scale Multi-Domain Psychophysical Investigation
Interoception-the sensing and perception of the internal viscera-is widely cast as a transdiagnostic mechanism linking brain-body interaction to mental illness. Prevailing models propose that altered ...

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.
A much-needed joint effort from five labs to see which behavioral effects of psilocybin in mice are reliable, and which may be spurious 🐁🍄 @theborislab.bsky.social @mazenkheirbek.bsky.social @indigenerd.bsky.social Vikaas Sohal and Stephan Lammel 👏 www.biorxiv.org/content/10.1...
