      Extracting quantitative information on neuronal signals by non-invasive imaging is an outstanding challenge for understanding brain function and pathology. Still, currently established fMRI methods such as BOLD or diffusion, measure neuronal activation indirectly. Stimulus-induced rotary saturation (SIRS) has been recently proposed as a promising tool to detect neuronal fields and reconstruct functional connectivity using MRI. The principle of the technique is based on a double resonance effect produced when the Larmor frequency induced by a Spin Lock (SL) preparation pulse matches the frequency of an oscillating neuronal field.

      In this talk, I will present the concepts of magnetic resonance-based neuronal current imaging and the current state of the art in developing this technique. In addition, I will show the potential and limitations of its application in clinical practice.

      The lecture will be held as a zoom meeting, please connect using:
