We had a great session on multiband/SMS fMRI acquisitions in Vancouver at OHBM 2017. The speakers kindly allowed me to link to their slides here:
Benjamin Zahneisen spoke on the "Basics of Simultaneous Multi-Slice Imaging: SNR properties, g-factor penalty, multi-band artifacts, and other challenges associated with high temporal resolution".
Benjamin Risk spoke on the "Impacts of multiband acceleration factors on sensitivity and specificity".
Renzo (Laurentius) Huber spoke about "Recent experiences using SMS imaging in high-res fMRI studies".
