The new Nexstim Navigated Brain Stimulation (NBS) System creates an accurate and detailed map of the critical functions of the cortex using a standard MRI brain scan.
NBS uses stereotactic MRI-guided transcranial magnetic stimulation (TMS) to non-invasively excite precise areas of the cortex. Sophisticated, real-time data processing and modeling enables unsurpassed accuracy and control of the electric filed (E-field) inside the brain. Integrated EMG monitoring instantly shows the responses to stimuli in the central nervous system (CNS) and the peripheral nerves. NBS results are presented as detailed color maps of the critical eloquent areas visualized in a 3-D rendering of the brain.
NBS allows confident interpretation of measurement results since it is a direct method, like electrocortical stimulation. Avoiding the uncertainty of indirect methods, like fMRI for example, is a crucial advantage in neurosurgical decision making. NBS also performs cortical mapping faster and more cost-effectively than alternative functional imaging modalities.
The Nexstim NBS System offers neurosurgeons a safe and painless alternative to direct cortical stimulation that can be performed in comfort prior to surgery. 3-D cortical maps help visualize surgical strategies and give additional information to help patient and physician discuss outcomes.
Nexstim NBS has a wide range of other diagnostic applications, including testing for motor tract integrity following stroke.
