The inomed ISIS Mer System is a micro electrode recording system used in conjunction with deep brain stimulation and extracellular recording procedures. The configuration of the system is sufficiently flexible to fit in most operating room environments. Its modular features make it the ideal tool for conducting intraoperative interventions. Viewing the system's bright and clear display of signal recordings can be just a step or two away, allowing for a fast and precise reaction to any situation that requires it. System setup is accomplished in just a few easy steps. The MER system allows for optimal target location in the brain area enabling the user to perform a professional target analysis. Clinical effects in the target areas can quickly and precisely be evaluated due to the ease of electrode selection.
