We developed fast MRI methods facilitating concurrent
electrophysiological recordings and fMRI with high
spatio-temporal resolution (500ms / 750m) and full
brain coverage in macaques. The significant improvements
in MR signal sampling efficiency without and with the
use of parallel imaging are demonstrated by presenting
activation maps and time-courses of fMRI experiments
using a simple visual stimulation paradigm.
