Abstract

In a method for spatially resolved measurement of the electric activity of nerve cells by means of magnetic resonance, and a device for implementation of the method, a series of MR signal sets for the acquisition of spatially resolved MR signals is obtained, the phase shifts of the MR signals are determined, the phase shifts including shifts arising from magnetic field changes that are caused by the electric activity of nerve cells, and the event phase shifts of the MR signals are evaluated by a correlation of the MR signals with events that cause the electric activity.
