Multi-echo fMRI experiments were performed at 7T with and without REST slabs. Signal changes upon functional activation were measured at TE = 0 ms as a measure of functional CBV change. Simulations were also conducted to study multi-echo fMRI signal characteristics and its dependence on functional CBV changes
