Academics in Assyria in the 7th c BC complain that admin is preventing them from doing research and teaching

My first post into the bsky void, the first preprint of my PhD! A novel task to bridge learning and effort decision-making. Of course, we find that effort choice is sensitive to prior learning, but this integration of beliefs into action is affected by anhedonia. doi.org/10.1101/2025...

Fascinating and clinically important new paper. It highlights both reassuring and concerning findings on the cardiometabolic effects of #antidepressants. Should post-initiation monitoring focus more on #metabolic changes than QTc? www.thelancet.com/journals/lan...

Great review on The Genetics of Human Handedness: Microtubules and Beyond www.cell.com/trends/genet... - handedness is such an interesting phenotype!

Out today at Neuron, our experiments show that frontal cortical representation of economic variables is jointly determined by spatial organization and downstream connectivity of neurons, revealing a structured, multi-scale code for economic variables. www.cell.com/neuron/fullt...

1/ To explore or to exploit? I’m excited to share my new preprint with @tobiasuhauser.bsky.social and @micahgallen.com, correlating variations in cortical microstructures with individual differences in exploration-exploitation behaviours, using a gamified task! 🧵 www.biorxiv.org/content/10.1...

Really 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).

“Israeli Forces Kill 198 Palestinians in Gaza Over Three Days” It’s a genocide. Daily endless massacres, largely ignored in the West.

Familial confounding in the associations between maternal health and autism www.nature.com/articles/s41... - drawing causal conclusions from observational studies is not a good idea

BlueSky friends, forgive me for not posting much on here. I'm standing for President of the RCPsych in the elections next March. I'm still speaking and listening to friends and colleagues about what is important, but you can learn about what I would do if successful here: www.profrobhoward.com

New paper out in @journal_ad (led by Guy Gitlin-Leigh). @profrobhoward.bsky.social We conducted the first systematic review + meta-analysis on whether monoclonal antibody therapies for #Alzheimer’s (AD) & #Parkinson’s (PD) affect risk of depression. Link: journals.sagepub.com/doi/10.1177/...

🚨Our preprint is online!🚨 www.biorxiv.org/content/10.1... How do #dopamine neurons perform the key calculations in reinforcement #learning? Read on to find out more! 🧵

Excited to share this new preprint on the Predictive Modelling of Depression Treatment Response using Individual Symptoms and Latent Factors with @clairegillan.bsky.social fresh up on @medrxivpreprint.bsky.social www.medrxiv.org/content/10.1...

How does the brain decide? 🧠 Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc. After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up. rdcu.be/eGUrv

Pretty sure the only large blinded RCTs of #GLP-1 agonists in psychiatry/neurology have been in #schizophrenia and #Parkinson’s disease—both found no core symptomatic benefit. Fantastic drugs for metabolic health, but current trial evidence for broader neuro/psych use sadly isn’t promising.

‘Maintaining share of #NHS spend on mental health, will be critical although it fell last year and will again this year. It likely will continue to do so over the next 3years. I hope I am wrong.’ Worrying times for NHS #mentalhealth care which barely featured in the 10yr plan…

In #DeepBrainStimulation the two major developments across the last decade have been 1. Adaptive DBS and 2. Connectomic DBS In a @natrevneurol.nature.com article with @julianneumann.bsky.social, we ask: Could the two be united into a common framework? www.nature.com/articles/s41... A 🧵

Thrilled to see our TinyRNN paper in @nature! We show how tiny RNNs predict choices of individual subjects accurately while staying fully interpretable. This approach can transform how we model cognitive processes in both healthy and disordered decisions. doi.org/10.1038/s415...

Comparing a treatment to waitlist is an extremely low bar. Essentially it isn't even a bar as objectively ineffective treatments (e.g. homeopathy) outperforms waitlist. www.sciencedirect.com/science/arti...

At last! Why did this take decades to introduce when most of Europe & the US rolled it out long ago? Especially important given emerging evidence linking VZV vaccination with protection against neurodegenerative disorders. #chickenpox www.bbc.co.uk/news/article...

On the left is a rabbit. On the right is an elephant. But guess what: They’re the *same image*, rotated 90°! In @currentbiology.bsky.social, @chazfirestone.bsky.social & I show how these images—known as “visual anagrams”—can help solve a longstanding problem in cognitive science. bit.ly/45BVnCZ

What's not to like about this image, presented at AAIC and touted as showing lasting and expanding (maybe, even clinically important) efficacy of lecanemab treatment through 48 months of treatment - but only if you start treatment early and don't stop?

Wonderful information about SEVERE limitations of "real world data". Telling in the RWD sphere is unwillingness of its practitioners to add a model parameter to represent unknown bias as exemplified in fharrell.com/post/hxcontrol => uncertainty intervals for treatment effects properly wider.

Obviously ridiculous from a ridiculous person — but this seems to reflect the consensus on social care across all major UK parties. AI has become the opium of a political class that is out of ideas and too fearful to face the real challenges of our time.

A landmark volume, The Handbook of Dopamine, is now online: www.sciencedirect.com/handbook/han... Big kudos to the editors, Stephanie Cragg and Mark Walton, for putting this together.

The replies to this post, even on here, even moreso on X, are so depressing to me. We live in a world where cities have never been safer and a minority of people are denying themselves a lot of delightful experiences because they’ve gone mad online.

It'ssssss PREPRINT THURSDAY! (Sadly not a thing). Approximately an era ago, I spent a *lot* of time discussing the assumptions that underpin the field of #ComputationalPskychiatry with the brilliant @jonroiser.bsky.social and @olijrobinson.bsky.social osf.io/preprints/ps...

V important meta-analysis doi.org/10.1001/jama...: Discontinuation symptoms 1 week post stopping antidepressants was below the threshold for clinically significant discontinuation syndrome. Later worse mood is likely depression relapse @jfhayes.bsky.social @sameerjauhar.bsky.social.

Excited to share our new review on how neuroimaging and computational models can help uncover how people see what they want to see, now out at @cp-trendscognsci.bsky.social! It was a blast writing this with Haena Kim and @iancballard.bsky.social www.sciencedirect.com/science/arti...

Important study & big step forward for treatment-resistant #depression. 48-week RCT, #pramipexole showed a ~4-point QIDS-SR benefit over placebo. Less hype, but bigger effects than psychedelic trials, for a scalable option that’s already available to clinicians! www.thelancet.com/journals/lan...

First paper from my lab @upenn.edu (open access) @ Biological Psychiatry w/ @emilyrperkins.bsky.social [email protected] We discuss the need to falsify theories of biology predicting syndromes vs. syndromes in ways that allow both to be true 🧵1/10 authors.elsevier.com/sd/article/S...

🍝 A package I love, {datapasta}, came up at #CascadiaRconf this weekend, so I wanted to share a little example of it in action. It's an addin (but also a pkg w/ some funcs), so showing is better than sharing code. Thanks for the awesome pkg, @milesmcbain.bsky.social! #rstats #databs

Here is Kim's (@ucsdcooperlab.bsky.social) well-read @dev-journal.bsky.social Review from last year's special issue on uncovering developmental diversity. If you would like your own copy of the special issue, you can pick one up now at #2025ICDB #2025SDB - booth #4.

Here are my thoughts on how one must demonstrate just the statistical validity of found clusters, before clinical validity is even attempted: www.fharrell.com/post/cluster... #Statistics

Medicine and #psychiatry in this country changed significantly today. Let’s hope this shift doesn’t come at the cost of quality #palliative care, or lead to premature, unnecessary deaths among the vulnerable, poor, and mentally ill. Time for the Lords to earn its keep…

In our preprint "Limited evidence for reduced learning rate adaptation in anxious-depression, before or after treatment", led by @stephsuddell.bsky.social and Lili Zhang, we fail to find a robust association between anxious-depression and learning rate adaptation osf.io/preprints/ps...

This was hard work, but ultimately there is support in the literature that engagement of different RL processes by serotonergic and dopaminergic/noradrenergic pharmacological interventions may be a promising route to follow. The @relmed.bsky.social study will do just that.
