Exploring Cellular Water Dynamics associated with Potassium Ion Changes Using Magnetic Resonance Imaging

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.

Update on the reproduction and interpretation of DIANA fMRI

The paper reproduces DIANA fMRI experiments in anesthetized mice and analyzes the signal origin, suggesting PSS oscillations may generate DIANA signals rather than direct neuronal responses.

Direct imaging of neural activity reveals neural circuits via spatiotemporal activation mapping

This study demonstrates that DIANA fMRI can reveal multiple neural circuits through spatiotemporal activation mapping in anesthetized mice.

Responses to membrane potential-modulating ionic solutions measured by magnetic resonance imaging of cultured cells and in vivo rat cortex

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.

In vivo direct imaging of neuronal activity at high temporo-spatial resolution

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.
