Using neuroimaging data to predict future brain health. One of the cool things here is that we can train an image-informed model which can then outperform models trained only on assessments, *even from individuals without imaging data available* (

@JAMAPsych Great article on EEG. However IMO there *is* evidence of the utility of fMRI spatial specificity for clinical utility (cf. lots of subcortical in the below). Also, we don't need 40 min of data, network constraints yield highly reliable fMRI in 5-10 min.

Scaling and comparing brain networks via constrained IVA....provides the best of both worlds, data-driven, subject-specific, yet also correspondence among subjects.

@GrattonCaterina 👍check also these relevant papers: null models/kurtosis: short rest scans replicate & predict: states canonical and differences replicate: states overlap:

If folks are interested in linking macro-environment/satellite data to brain data see our study here ( . You can also play with it yourself, the data are released as part of ABCD data release 5.0. ;-)

@fMRI_today It is important...but slight quibble with 'emerging', we and others have been looking at various ways spatial properties of networks vary in brain disorder for over 20 years now (cf . And spatial dynamics are also important (!

@ItaiYanai Fraud is also about intent to deceive...the scientific paper is rather an attempt to describe a process that then needs to be replicated by others. It has flaws of course, modern papers are trying to improve transparency via embedded code and data.
