FWIW: our group collects a lot of highly-accelerated fMRI at 3T and 7T; as you know the single band reference images have a ton more contrast than the accelerated data. However, I've never once needed to use them because afni_proc does so well with alignment and blip-up/down distortion correction.

A lot of people think that every international student admitted means one fewer spot for domestic students, when the opposite is more likely true - the tuition revenue international students bring allows public universities to provide substantial discounts to domestic students, improving access.

Longer fMRI brain scans boost reliability—but only to a point
Around 30 minutes of imaging per person seems to be the “sweet spot” for linking functional connectivity differences to traits in an accurate and cost-effective way.

i'm collecting a super small FOV and want a lateralized fiducial marker that's not focal like a vitamin E capsule but rather like a "strip" so it'll be present despite where I place the acquisition window. ideas? dielectric pads are too thick and obviously i wouldn't want to place only 1

A human brain network linked to restoration of consciousness after deep brain stimulation - Nature Communications
In people with severe brain injuries, stimulation restored consciousness by engaging a deep brain circuit for wakefulness—revealing a target that may also guide treatment in stroke and epilepsy.
