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. 🥁

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

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.

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.
