Exciting that interpersonal computational psychiatry offers an explanation for how biased cognitive processes lead to differential negative symptoms, @dr_rick_adams. Thanks @TheLancetPsych and colleagues. Might be interesting alternative to a data-driven view!?! @INM7_ISN @bttyeo

We propose an interpersonal computational framework that (1) leverages the active inference framework to model aberrant social coordination and (2) incorporates dynamical system models to dissect intrapersonal and interpersonal synchronisation to inform a statistical model.

1/9 Paper is out rdcu.be/cNHoL Here's some takeaways including new tidbits (good & bad!) since the preprint & even after the paper was accepted. Large sample sizes are helpful for individual-level prediction. We have known that for quite some time, but the recent...

1/5 Our new preprint doi.org/10.1101/2020.0… uses meta-learning to boost functional connectivity based prediction of *NEW* phenotypes in small samples. We achieve 100%-400% improvements in many scenarios! @hetong93 @AvramHolmes @anlijuncn @danilobzdok @AvramHolmes @INM7_ISN

#Autism is often associated with an excess of synapses: but how does this trait affect large-scale circuit function? Here's what we found by modelling autism-related pruning deficits across-species🧠🐭 ➡️tinyurl.com/y2yfj74o By @MarcoPagani1985 @mvlombardo & al. Thread 1/n

Phenomenal work from our lab & collaborators led by @jchen_ML_Psy: Connectivity patterns of task-defined networks allow individual prediction of dimensional schizophrenia psychopathology & link to molecular architecture Short thread on the highlights ⤵️ biologicalpsychiatryjournal.com/article/S0006-…

Our new work is out! We found severe prolonged nausea and vomiting in pregnancy was significantly associated with emotional and psychiatric problems, reduced global cognitive performance and low cortical volume in the children. Hoping these findings will help pregnant mothers.

New #OpenAccess research showing that severe nausea and #vomiting during #pregnancy is strongly associated with #cognitive problems in #children. Read it here: bmcmedicine.biomedcentral.com/articles/10.11…

Thx @INM7_ISN ! An amazing & important tool for #Schizophrenia research. Wonderful collaboration @MHASC1 @CognitionLille Read the #OA paper here: sciencedirect.com/science/articl…
Simon Eickhoff@INM7_ISN

PANSS sub scales (positive, negative, general psychopathology) are widely used in basic & clinical research on #Schizophrenia ... but do not represent natural dimensions ! Replacing them with robust & generalizable factors is now easy with our new tool: webtools.inm7.de/sczDCTS/

New preprint! 👇 We related connectome architecture to patterns of atrophy in the common epilepsies and identified syndrome-specific disease epicenters 📌 Our @enigmabrains analysis pooled data across 19 international sites and included 1,021 patients and 1,564 controls 🌎🌏🌍
