This study uses MRI to show that potassium ion changes affect cellular water dynamics differently than hypoosmotic stress, with distinct effects on free and bound water pools.

This study uses MRI to measure responses of cultured cells and in vivo rat cortex to ionic solutions that modulate membrane potential, finding changes in T2 relaxation time and bound-to-free water proton ratio.

This paper introduces DIANA-fMRI, a method for high-temporal and spatial resolution imaging of neuronal activity in vivo, demonstrating its ability to capture spiking activity and propagation in mice brains.
