We find that ADC-fMRI shows no detectable correlation with hemodynamic fluctuations resulting from changes in CO2 concentrations, while BOLD does - even at matching SNR levels. 👌
This makes ADC-fMRI a unique and complementary functional contrast to BOLD.

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. 🥁

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.

The most productive researchers are those who can engage in a critical exchange without letting their ego cloud their judgement

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.

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 🧠 ...

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.

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.

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

Apparent Diffusion Coefficient fMRI shines light on white matter resting-state connectivity compared to BOLD - Communications Biology de Riedmatten et al. propose apparent diffusion coefficient functional MRI as a novel contrast for assessing functional connectivity in both grey matter and white matter, addressing the limitations of...

📰 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.

Mapping Activity and Functional Organisation of the Motor and Visual Pathways Using ADC‐fMRI in the Human Brain This article validates ADC-fMRI as a tool complementing BOLD-fMRI, detecting neural activity via neuromorphological coupling. In experiments with motor and visual stimuli at 3 T, ADC-fMRI was shown t...

New paper from the lab, led by J. Nguyen-Duc!
Apparent Diffusion Coefficient (ADC)-fMRI complements BOLD in mapping motor pathway activation *and* recovers the functional organization of the visual dorsal & ventral streams.
