Abstract
A method is provided for operating a magnetic resonance apparatus comprising a magnetic stimulation device, the method comprising bearing a region of a central nervous system of a living examination subject in an imaging volume of the magnetic resonance apparatus, whereby this region is to be imaged, operating the magnetic stimulation device for stimulating at least one prescribable location of the examination subject outside of the region to be imaged and generating a functional magnetic resonance image of the region to be imaged for imaging a neuronal activity of the central nervous system, whereby said neuronal activity is initiated by the stimulation.
