There is no such thing as pseudoanonymized data under the GDPR; it is either personal or anonymous @cyrilrpernet.bsky.social #OHBM2024
picture of the presenter and a slide stating that brain imaging is 'personal data' according to the GDPR

Do different analysts reach similar conclusions given the same fMRI data and pre-defined hypotheses? Nope, 70 independent teams chose 70 different analysis pipelines!
@rotembot.bsky.social #NARPS #reproducibility #variability #OHBM2024
slides stating that there is a lot of variability in fMRI analysis methods Some solutions about variability: transparent reporting, code sharing, data sharing, preregistration

Research participant samples are more 'weird' than representative @Chang-PengHu #OHBM2024
A world map shows that most participants in research study are only from europe, north america and china A bar graph depicts that the repartition of participants per country in research study does not represent well the world distribution

And last but not least:
-Individual characteristics such as age, gender, and TIV *outperfom* rsfMRI in cognitive prediction !

Useful reminders from @sbe.bsky.social about #neuroimaging analysis #reproducibility at #OHBM2024:
- Different atlases lead to different connectivity matrices.
- The target *massively* matters.
- ML algorithms just *love* shortcuts.

Still one day to come meet us at Poster #1905 !

Many thanks #OHBM2024 for this opportunity to present our work on #MetaAnalysis for #neuroimaging #multiverse

So many QC options (also @PaulTaylor during #OBHM2024 #Brainhack)
June 25, 2024 at 2:41 AM
jlefortbesnard.bsky.social
So many papers claiming vmPFC signal is linked to this or that behavior, but is it really when the vmPFC appears empty is many fMRI scans? => QC matters a lot! AFNI soft can help, check out their online demo : afni.github.io/qc-demo-repo/
@PaulTaylor during the #OHBM2024 #Brainhack
VMPFC signal absent

The million $ question addressed by @lucinauddin.bsky.social #OHBM2024
Despicts the million dollars question: is global signal signal or noise?!

Polarization is also why we should care about subjective experience @esfinn.bsky.social #OHBM2024
Depicts photos of 2 groups of people interpreting "black live matters" in two different ways. The box in the middle depicts that almost 50% of participants saw racism when there was not, and failed to see racism when there was.

Global signal is anticorrelated with vigilance, this might be what you want but this might also be the elephant in the room @ThomasLiu #OHBM2024
Depicts that global signal is the elephant in the room and everybody sees it from its own point of you

We should care about subjective experience even if interested in group differences, using thought sampling resting states instead of resting states alone is already a great start @esfinn.bsky.social #OHBM2024
Top: depicts that thought sampling resting states lead to better prediction of behavior compared to resting states alone. Bottom: depicts that naturalistic task (e.g., watch a movie) is a good tradeoff compared to task or resting state alone to study variability in subjective experience still with some control over it

Aim for computational reproducibility, and even better for replicability !
@cmaumet.bsky.social, #Empenn, #Inria, #Irisa, #IABM24 #neuroAI #neuroskyence #neuroimaging #MRI #Reproducibility
Picture of speaker + slides, slide illustrates computational reproducibility (get same results using same data and same analysis) and replicability (get similar results using different data and different analysis)

Deep learning -not better- than classical ML models for classifying psychiatric diseases using MRI even with N=1500 !
