Purpose There is a need for high resolution non‐invasive imaging methods of physiologic
magnetic fields. The purpose of this work is to develop a MRI detection approach for non …

Extracting quantitative information of neuronal signals by non-invasive imaging is an
outstanding challenge for understanding brain function and pathology. However, state-of-the …

Spin-lock based functional magnetic resonance imaging (fMRI) has the potential for direct
spatially-resolved detection of neuronal activity and thus may represent an important step for …

Purpose: In the recent past, spin-locking MRI experiments were successfully applied for the
direct detection of sinusoidal magnetic field oscillations in the sub-nT range. In the present …

Resonant absorption during spin-lock preparation can be used to measure tiny oscillating
magnetic fields acting as direct evidence of electrical neuronal activity. Different spin-locking …
