New paper in Imaging Neuroscience by Sam Parsons, Rogier Kievit, et al:

Longitudinal stability of cortical grey matter measures varies across brain regions, imaging metrics, and testing sites in the ABCD study

doi.org/10.1162/imag_a…

Has anyone in my network used a mobile breathalyzer and/or a wrist-worn BAC sensor in an EMA study? Curious about tradeoffs between burden/compliance and accuracy.

I am constantly thrown-off by login.gov. I have to use it to get into ERA commons now, but login.gov throws errors for NDA, and I instead have to use ERA commons! What gives? And of course I have to always remember to clear browser's cache first 🤦‍♂️

fMRI folks - I feel like I saw a paper a while back that assigned regions in different structural parcellations (Desikan, Destrieux, Glasser) to resting state networks. Now of course I can't find it. Does that ring any bells for anyone?

From the supplement of the paper I'm writing - 2-year longitudinal stability of Neuroimaging IDPs from the ABCD study.

Am I correct that there are currently no accepted ways for computing a confidence interval for the correlation between a pair of brain maps collected on two different samples?

Of course if they're from the sample you can just bootstrap.

Can GWAS identify new treatments for psychiatric disorders? AlexanderSHatoum shows here that they already identify existing ones!

A quick data simulation/visualization about being cautious when using difference scores.

Very cool paper. Reminds me of the piranha problem as well - that the total variance explained cannot surpass 100%, which places constraints on the distribution of possible effects stat.columbia.edu/~gelman/resear…

Had a lot of fun helping out as a statistical collaborator on this cool work!

What might you do after a PhD? I interviewed 53 people and mapped out career paths
(Interviews are themselves available too!)
