New review paper on theory of mind/mentalizing and spontaneous speech/language. Led by Chaimaa El Mouslih, and co-authored with @vegashodgins.bsky.social and @lenapl.bsky.social www.mdpi.com/2076-328X/15...

Check out this 🆕 paper form @lenapl.bsky.social et al showing that speech spectrograms can track negative symptom severity in schizophrenia www.nature.com/articles/s44...

🚨 NEW RESEARCH! ⚕️ 🩺 🧠 Elleuch et al. explore the association of grammatical challenges in people with Schizophrenia in a systematic review and meta-analysis of 45 studies. https://bit.ly/4kZnq66 @lenapl.bsky.social

One of the largest longitudinal study of computational speech and language features and psychosis from @stanglab.bsky.social Tang & colleagues! www.nature.com/articles/s44...

#ThisWeekInNPP This study identified a prefrontal-limbic structural covariance network with ⬇️ gray matter volume specific to treatment-resistant schizophrenia, linked to serotonergic, glutamatergic, histaminergic, & opioid receptor distributions 🧠 www.nature.com/articles/s41...

www.nature.com/articles/s41... People with schizophrenia that is resistant to treatment may have specific prefrontal-limbic brain deficits linked to non-dopaminergic neurotransmitter systems—highlighting the need for therapies beyond antipsychotics. #schizophrenia #neuroscience #mentalhealth

Very, very obviously we need to emphasize science-informed preventative strategies. Public health experts – myself included – have focused on this for decades! But phrase "root causes" long ago morphed into a red flag for bunk. 🚩 news.immunologic.org/p/real-root-... @drandrealove.bsky.social‬👇

We show cannabis use disorder is associated with higher midbrain neuromelanin, where such an increase is associated with #psychosis severity. The higher the use, the greater the putative dopamine turnover. Led by Jessica Ahrens @healthsciences.mcgill.ca IPN jamanetwork.com/journals/jam...

www.sciencedirect.com/science/arti... We see a prominent excess of first-person pronouns in #schizophrenia, with no excessive inter-individual variability. While not a direct comparison, this effect (d=0.89) is >> than striatal dopamine excess or prefrontal glutamate reduction reported to date.

Congrats all! A proud moment for ceymh-cesmj.ca/youth-family... who shaped 2 of the 4 funded grants this time!

Well done, Tiana! douglas.research.mcgill.ca/news/hsi-wei.... Thanks to @sylvainbaillet.bsky.social & @magnetokrishio.bsky.social 's awesome groups - we are getting full-time into the oscillatory dynamics of psychosis.

I've been working with the Wilson-Cowan neural mass model for a while now and, over time, I've accumulated a bunch of tools to explore/visualize it. I recently decided to collect it all into a github repository available here if anyone is interested: github.com/NeuroLife77/...

Happy 30th birthday year to SPM!! 🎈🍰 To get the party started, we are delighted to announce SPM 25.01, a major new version of the open-source neuroimaging software. Read the preprint to discover what's new arxiv.org/pdf/2501.12081 and download SPM for free from Github github.com/spm/spm/rele...
