We’ve developed and validated a TMS/fMRI setup which allows us to manipulate and measure brain activity at the same time by combining Transcranial Magnetic Stimulation (TMS) with functional Magnetic Resonance Imaging (fMRI). A dedicated MR coil array allows for high-sensitivity fMRI, particularly at the site of stimulation. Contrary to the standard birdcage approach, this coil has excellent imaging quality at the stimulation site; and due to its flexibility, the new coil can be easily combined with neuronavigation within the MR scanner to allow for accurate targeting in TMS/fMRI experiments.

This dedicated MR coil array is distributed via Magventure. It is compatible with the MRi-B91 coil, MagPro stimulator and can be combined with current neuronavigation systems.
