Hey @grok, roast me.

@maier_ak unklare aufgabe, das kommt darauf an von welcher seite man anfängt zu sägen.

Dreisatz, anyone? 😂

fMRI signals “up,” but neural metabolism might be going “down.” In our @NatureNeuro paper, we show that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes. rdcu.be/eUPO8 funding @ERC_Research 🧵:

Thousands of Brain Imaging Studies Might Be Wrong A group led by researchers from Germany have discovered that about 40% of signals in conventional functional MRI (fMRI) scans don’t align with brain activity levels. These scans detect changes in blood flow, and assume that more blood flow means that neurons use more oxygen and fire more. But the new study shows that in regions like the brain’s “default mode network” (active during daydreaming or memory recall) neurons can become more active just by pulling more oxygen from blood, without increasing blood flow. The researchers figured that out with a study on over 40 healthy volunteers which also used a more advanced measure for blood oxygen consumption. This means that the results of thousands of studies done in the past decades might be misleading. This is more bad news for a field that previously suffered through the infamous “dead salmon” study from 2009, where researchers placed a deceased Atlantic salmon in an fMRI scanner, presented it with photos of humans in social situations, and detected apparent brain “activity” due to statistical errors

The German company that built the forklift used in the Louvre robbery uses a photo of the heist to advertise itself: “When things need to be done quickly.” 😂😂😂

@michal_leskes @ShakkedSchwartz @ayanmaity94 @NokedLab Cool ! After CEST comes DEST. waiting for FEST!

Just out: our new study where we use NMR to directly detect lithium adsorption at the electrode- electrolyte interface. This took us some time to figure out and I'm super proud of the result! congrats to @ShakkedSchwartz, @ayanmaity94 &collab @NokedLab🔋🧲 pubs.acs.org/doi/10.1021/ja…

I see the term “ablation” used in experimental sections of computer vision papers to describe just about any experiment, maybe because it sounds fancy. But to ablate something really means to cut it out or destroy it (typically human tissue). If you take your algorithm and remove (ie cut out) parts of it and evaluate the result, the you have an ablation study. Anything else goes by another name.

Me coding assisted by AI:

Surfing the Pulseq wave in the FAU MRIpulseq hands-on course. We explored all flavors of FLASH, TSE, bSSFP before every student solves an own seq exercise. Well done @UniFAU students. All course material and our MR-zero simulator is online: github.com/mzaiss/MRTwin_…

Qualitative researchers when they see statistics

we are so back

I even know who acquired it.

Me googling GRAPPA recon in BART during the group meeting

@maier_ak got my first convincing application with references that do not exist in the cv.

Just started to reply to template mails that address me as "Dear prof," with my own template with "Dear [Insert Name here]".

Give the students an MRI sequence and they can do one project. Teach the students Pulseq programming and they can do new projects for their whole life. Our Pulseq course + MR-zero simu this #FAU-semester is Sept 1-12. Save the date and join virtually: buff.ly/cF59vzw

@maier_ak @SiemensHealth It certainly will boost the car industry as what attracts cars also attracts car companies!
