The history and future of resting-state functional magnetic resonance imaging - Nature This Review provides an overview of the history of resting-state functional MRI research, which has helped to reveal the spatiotemporal organization of the brain, and discusses how it can contribute f...

When I first started working with resting state fMRI as a postdoc, there was a lot of skepticism about what we could learn from it. 20 years later, it's hard to imagine where the field of neuroscience would be without it. Here's a summary 🧠 www.nature.com/articles/s41...

fMRI must break out of its silo We need to develop research programs that link phenomena across levels, from genes and molecules to cells, circuits, networks and behavior.

The scientific community needs to develop processes to support, hire and retain researchers whose work sits between traditional fields of study, writes @avramholmes.bsky.social

Most people haven’t heard of this test, which is available in the US. It accurately predicts Alzheimer’s (not just if there’s a risk, but when). It is modulated by exercise and likely other lifestyle factors.
Here’s (almost) everything we know about it

It's shocking how little is known about the brainstem red nucleus. In our new paper β€œThe human brainstem’s red nucleus was upgraded to support goal-directed action” out now in @naturecomms.bsky.social we show that current thinking on the red nucleus is in need of a serious upgrade. rdcu.be/ehbOy

Is generalized epilepsy a seizure of the whole brain or a specific brain network?

In our new paper out now in @naturecomms.bsky.social, we investigate this by combining brain abnormalities and DBS with the human connectome.
