CortexCast replays real 64-channel EEG from people imagining left- or right-hand movements, and decodes the imagined side in the browser as the recording plays.
The recordings come from the PhysioNet EEG Motor Movement/Imagery dataset. Each electrode’s mu (8–12 Hz) and beta (13–30 Hz) power is computed live, and a rotating head shows it as a scalp map interpolated on the graphics card. When a person imagines a movement, activity over the opposite motor cortex drops. The decoder compares electrodes C3 and C4 to decide left or right, and is correct about 60–66% of the time, where chance is 50%.
It is a replay of recorded data with a live read-out, not a closed-loop brain-computer interface.
Data: PhysioNet EEG Motor Movement/Imagery dataset.
Lab demos are working experiments that show the methods behind our products. The same techniques can be built into software for your organisation.
