- Reposted by Claire O'CallaghanExcited to share newly minted PhD Anu Korukonda's tour de force thesis work describing the impact of pathogenic tau on #locuscoeruleus function in a mouse model of early #Alzheimers. A must for #BlueSpot researchers! www.biorxiv.org/content/10.6... 1/3
- Reposted by Claire O'CallaghanNow in press one of my last PhD projects! We traced the neurobiological profile of fMRI BOLD signal variability, a measure that has been related to age, behaviour, disease status, but had not yet been fully contextualised within the brain's multiscale architecture. www.nature.com/articles/s41...
- Reposted by Claire O'CallaghanOur latest preprint on how regional cellular, molecular, and other forms of heterogeneity shape macroscopic wave dynamics is now out: www.biorxiv.org/content/10.6... For a full thread, see: x.com/_victorbarne...
- Reposted by Claire O'CallaghanThe extended version of my thesis procrastination project/subcortex visualization package is out now in both Python and R, now that I’ve graduated 🤠 This figure shows the 9 atlases included (and counting)!

- Reposted by Claire O'CallaghanWhy do some worms graze on bacteria while others hunt and kill? Our study, published today in Nature, reveals how predatory aggression evolved in nematodes. Led by @gunizgozeeren.bsky.social and @leoboeger.bsky.social across the @jameslightfoot.bsky.social and @monikakscholz.bsky.social labs.
- Reposted by Claire O'CallaghanExcited to share our new preprint! We explore the link between the locus coeruleus (LC) and arousal for astrocytes, pyramidal cells, interneurons in the hippocampus. A fantastic collaboration with @sianduss.bsky.social @bohaceklab.bsky.social, and many others: www.biorxiv.org/content/10.6... 1/5

- Reposted by Claire O'CallaghanA major part of our future health & prosperity lies in medical research. There are billions of available dollars that can be used for vital medical science. Please join the campaign for our government to act urgently to fully disperse these funds: aamri.org.au/mrff/ www.theage.com.au/politics/fed...
- Reposted by Claire O'CallaghanThrilled this is out, led by former PD Cameron Ogg (now with her own lab at @rhodescollege.bsky.social!). It was a driven by a desire to see, in real-time, how LC activity/NE release influences downstream targets in behaving animals. SO hard to do, but Cameron did it! www.cell.com/cell-reports...

So if you weren't at OHBM, were there but happened to miss it, or if you did see it and just want to relive it all over again, here is your chance :) I'm quite fond of this one. www.youtube.com/watch?v=lP86...

- Reposted by Claire O'CallaghanWe used rabies virus 👾 to map how #psilocybin modifies long-range circuits 🧠, revealing network-specific reorganization that we didn’t expect. The full study is now online at Cell. @cp-cell.bsky.social Paper 👉 www.cell.com/cell/fulltex... Thread for a synopsis 👉 bsky.app/profile/alex...

- Reposted by Claire O'CallaghanReally interesting work by Bakhurin and colleagues challenging the reward prediction error hypothesis of dopamine: www.nature.com/articles/s41... I love this figure which both echoes and undermines the famous figure from Schultz et al. (1997).
- Reposted by Claire O'CallaghanAs I argue in #PlatypusMatters, Australia has the world's best mammals, but is sadly the worst place on Earth to be a mammal, with the planet's worst #extinction rate.
