The following is a non-exhaustive but more detailed list of data measured and input to diagnoses addressed by the Neocortex Digital screening report. Additional parameters will be measured, even if not included in this list. All services offered through the Neocortex Digital device are gamified, so that data are gathered while the patient visually interacts with a virtual true 3D environment. Services are tailored to individual patient needs through various selected videogames.
