### VIII COMPARISON TO THE PREDICATE DEVICE OF TECHNOLOGICAL CHARACTERISTICS
As shown in the Substantial Equivalence Comparison Table, the intended use, principle of operation and system components, method of contact, user interface, and software design of the Cumulus Functional Neurophysiology Platform compared to the NeuralScan System Primary Predicate are similar.
While the software components of subject device and Predicate are proprietary and thus different, each is evaluated according to FDA's software verification and validation processes. In addition, the specific design of the Cumulus headset is different from the Predicate, however, the recording methodologies used are common in clinical research and typically delivered using lab-suitable technologies (e.g. a PC and computer screen). The Cumulus system uses a mobile device to increase convenience of use and ease of deployment and provides a controlled platform with well-understood technical characteristics.
The differences, in comparison to the Predicate device, raise no new questions of safety and effectiveness.
# VIX CONCLUSION
Based on the comparisons shown in Substantial Equivalence Comparison table, the Cumulus Functional Neurophysiology Platform device is substantially equivalent to the Predicate NeuralScan System. The nonclinical data support the safety of the device system and the hardware and software verification and validation demonstrate that the subject device should perform as intended in the indicated environments.
