Mouse brain fMRI has made significant progress over the
last 10 years, but remains technically challenging and
requires further efforts to improve data acquisition. In
this work we demonstrate the use of visual stimulation
as a viable task for fMRI of the mouse brain, with
robust responses in the mid-brain (superior colliculus,
lateral geniculate nuclei), mapping the visual pathway.
We also examine the use of GE-EPI with multiple
snapshots (compressed segments) as a way of reducing
image distortion due to
