Layer-fMRI VASO worldwide

This blog post gives an overview of the scientific network of researchers that are using the VASO (vascular space occupancy) for applications in layer-fMRI. I tried to give an overview of all layer-fMRI VASO papers published so far and provide a map of all layer-fMRI VASO labs around the globe.

Popularity of layer-fMRI VASO across years and countries

The first layer-fMRI VASO studies in humans were presented in 2014/2015. In the five years that followed, VASO became a credible contrast for the emerging field of layer-fMRI.

Temporal evolution of VASO for layer-fMRI studies. The numbers are developing in one direction: ⇑ UP ⇑
As of today (Jan 2020) there are 31 labs around the world that are using layer-fMRI VASO with 25 published layer-fMRI VASO papers in peer-reviewed journals

The vast majority of layer-fMRI VASO research is happening in Europe, followed by Asia. The higher 7T density in USA is not represented in a correspondingly many layer-fMRI VASO studies. This it might be due to the medical-application driven research funding environment.
