This study shows that a single ECT session causes transient, reversible brain microstructural changes resembling vasogenic edema, which may precede neuroplasticity and therapeutic effects.

The paper examines how brain networks shift between intrinsic and extrinsic modes during rest and active processing using fMRI data from visual tasks.

This paper investigates quantitative functional sodium imaging (fNaI) to measure 23Na concentration changes during motor tasks, showing sensitivity to distributed functional alterations in brain regions.
