111. Renzo Huber: Layer-fMRI, high-resolution fMRI, and the delicate balance between gourmet chef and janitor

BJKS Podcast

Renzo Huber is a staff scientist at NIH. We talk about his work on layer-fMRI: what it is, how Renzo got into it, how to do it, when it makes sense to do it, what the future holds, and much more.
