Growing evidence that careful experimental design of ADC-fMRI yields functional information distinct from BOLD prompts the question of residual vascular sources. We thus analyzed the ADC- and BOLD-fMRI responses to non-neuronal vascular fluctuations. 🥁 Led by I. de Riedmatten & A. Spencer #FIREPATH

The most productive researchers are those who can engage in a critical exchange without letting their ego cloud their judgement https://go.nature.com/43g7nci

What an angry exchange with a reviewer taught me about arrogance and humility

Nature - I should have paused and asked myself some tough questions. Instead, I started to type.

First post on an exciting new manuscript online today @natneuro.nature.com - in collab with @lucinauddin.bsky.social and Catie Chang. We take a fresh look at the physiological dynamics associated with the global signal 🧠 ... www.nature.com/articles/s41... Read here: rdcu.be/ek01F

Autonomic physiological coupling of the global fMRI signal

Nature Neuroscience - The brain and body are necessarily connected. Here the authors show that brain blood flow and electrical activity are coupled with systemic physiological changes in the body.

The group has just published a new scientific article on #MRI transverse relaxation decay in subcortical grey matter: analyticalsciencejournals.onlinelibrary.wiley.com/doi/10.1002/...

Our first BSKY post and its a good one. Huge collaborative effort from the Diffusion Study Group @ismrm.bsky.social on "Considerations and recommendations from the ISMRM diffusion study group for preclinical diffusion MRI" led by @ijelescu.bsky.social & DSG team! Full papers below.

It's finally here! Use the Network Correspondence Toolbox to help contextualize your neuroimaging findings 🧠

A network correspondence toolbox for quantitative evaluation of novel neuroimaging results - Nature Communications

Here, the authors present the Network Correspondence Toolbox, which enables researchers to examine and report spatial correspondence between their neuroimaging results and widely used brain atlases.

📰 Out now in @commsbio.bsky.social! 🧠🧲🔍 Why should fMRI connectivity be limited to gray matter nodes? Using ADC-fMRI, we can robustly include white matter nodes and explore white-to-gray and white-to-white connectivity. Masterfully led by Inès de Riedmatten! #FIREPATH www.nature.com/articles/s42...

Apparent Diffusion Coefficient fMRI shines light on white matter resting-state connectivity compared to BOLD - Communications Biology

Wow, just wow. V different approach reveals numerous problems in Scientific Reports - cf deevybee.blogspot.com/2024/10/an-o... I do hope @springernature.bsky.social will start to publish reviewer reports and editor info as we suggested

Nikolay Tumanov@ntumanovxray.bsky.social · 2y ago

Bad. But how bad? I once asked myself, while finding fakes in the Scientific Report @natureportfolio.bsky.social. So I decide to "do my our research" - I took 100 articles in a row from Physical sciences that contains diffraction. Result - 15 fakes out 100. Details in the 🧵 #ResearchIntegrity 1/x

Have you registered for the ISMRM Workshop on 40 Years of Diffusion being held in Kyoto, Japan? Register on or before the 16 January early registration deadline and SAVE! Learn more & register: www.ismrm.org/workshops/20... #ISMRM #ISMRT #MRI #MedicalImaging #MagneticResonance #MR

🎈 COME JOIN US+LEARN ABOUT DIFFUSION MRI at this wonderful ISMRM workshop in Kyoto, Japan (Feb 16-20: 40 Years of Diffusion: Past, Present & Future): www.ismrm.org/workshops/20... 🔥 I'll do a talk on Generative AI + Diffusion MRI. The 2 fields are highly connected. So why study them? 🧵👇

🤩 Very excited for the 2025 Tissue Microstructure Imaging GRC! Special shout out to the vice-chairs, both of whom we're proud to count among our research center's alumni, & to Dmitry Novikov, who will speak about cellular-level imaging w/ #MRI. Program: www.grc.org/tissue-micro...
