How does BrainViz work?
BrainViz is a representation of an internal map of the head. It’s a surface contour map which shows activity at each sensor – it overlays the outputs with different colors and can’t record sessions. And you can see how each frequency is distributed across sensors or inside the head model.
At the core, we are detecting the FFT Frequency Bands from each sensor on the headset and visually mapping that onto the 3D model, BrainViz is a visualization tool for demonstrations and basic understanding of brain science, it gives a general sense of what’s going on in the brain (but is not a scientifically robust depiction).
