Neuroscience PhD student, Western University 🇨🇦. Multimodal fMRI 🐒 👳🏾♂️
pinned post!
Excited to share my first first-author paper in Nature Methods!🤩 A quest to solve fMRI–EEG interference revealed a hidden strength in the usually discarded “dummy” scans. That spark became SASS-fMRI — boosting sensitivity and enabling silent, flexible experiments.

Taking advantage of non-steady-state imaging to increase temporal SNR for fMRI - Nature Methods
A technique called SASS increases temporal signal-to-noise ratio for functional MRI by taking advantage of the time it takes to reach steady state when collecting functional images.

If the community wants, we have XA60 and VE12U versions we can make available as a C2P for Siemens scanners. And we have a Paravision 360 v3.6 available for Bruker. The processing code is equally simple and is posted with the paper.

Timing tweak turns trashed fMRI scans into treasure
Leveraging start-up “dummy scans,” which are typically discarded in imaging analyses, can shorten an experiment’s length and make data collection more efficient, a new study reveals.

A new open source nonsurgical head restraint for awake mouse fMRI from our lab led by Sam Laxer. TL;DR Scanning about 25% longer than with a surgically implanted head post, combined with some training gives good results. Happy mice = happy rsfmri networks.
