The Transmitter @thetransmitter.bsky.social · 16d

A method for capturing neuronal activity using fMRI excited the neuroimaging field but couldn’t be replicated. Today, the authors of the original paper retracted their work.

Authors retract Science paper on controversial fMRI method

Several MRI artifacts contribute to the neuronal activity signal picked up by the method, according to a preprint the authors posted this month.

AI chatbots are already biasing research — we must establish guidelines for their use now

The academic community has looked at how artificial-intelligence tools help researchers to write papers, but not how they distort the literature scientists choose to cite.

Computer crashed on the second day of the semester… great start. How’s your semester going?

Interesting fNIRS"NARPS"study. Interesting to see how research experience is correlated to confidence and results agreement.

Jonathan Peelle @jpeelle.bsky.social · Aug 5

38 research teams analyzed the same fNIRS data...Really nice visualization of the variety of processing pipelines people use from Meryem Yücel, Rob Luke, et al.:

"fNIRS reproducibility varies with data quality, analysis pipelines, and researcher experience"

www.nature.com/articles/s42...

Sankey diagram showing analysis steps for fNIRS. Snakes flow from left to right showing different design choices that many teams made during data analysis. Overall it looks like sort of a mess.

Someone should examine who continues to publish in NeuroImage — there might be a pattern worth exploring.

For those working with HCP data, how do you account for the acquisition phase as a factor? In our analysis, we found significant differences in ReHo values between the LR and RL phase acquisitions.
