Neural Navigator Mapping variant

Transcranial magnetic stimulation induces electrical currents in the brain non-invasively, which excite nerve cells and consequently produces action potentials. A motor evoked potential (MEP) can be registered if an electromyography (EMG) is recorded at the moment of stimulation. The Neural Navigator “Mapping” variant can exactly determine where the TMS coil evokes the strongest field, and visualize the MEP properties at that location on the brain surface. That way, maps of muscle-controlling brain regions in the motor cortex can be created of up to 8 muscles at a time (i.e. for each stimulus). With the use of this approach cerebral, spinal and peripheral pathways can be studied. Such tests are especially important for studying patients with brain damage after stroke or surgical procedures, or suffering from demyelinating diseases of the nervous system. This navigator variant requires a Neurosoft EMG unit. It is a co-development of Neurosoft and Brain Science Tools BV, and integration is seamless. This solution is cleared by the FDA for general purpose motor mapping in clinical use in the USA , CE certified for clinical use in the EU, and cleared for clinical use in Australia and Brazil.
