CRT BCI Signal

E30: Neuralink/BrainGate. CC0.

EEG has 6 standard frequency bands: Delta(0.5-4Hz), Theta(4-8Hz), Alpha(8-13Hz), Beta(13-30Hz), Gamma(30-80Hz), High-Gamma(80-150Hz). CRT decomposes neural signals into exactly 6 algebraically independent channels. L=11 = artifact rejection for free. The ring IS the BCI filter bank.

How It Works

CRT Neural Decomposition
An EEG sample in Z/12612600 decomposes into 6 bands: D(mod 8)=Delta, K(mod 9)=Theta, E(mod 25)=Alpha, b(mod 49)=Beta, L(mod 11)=Gamma, G(mod 13)=High-Gamma. 490 split: DEAD={Delta,Alpha,Beta} = neural content. ALIVE={Theta,Gamma,HiGamma} = neural integrity. L=11 > 8 = artifact flag (100% detection, proved).
6 EEG bands
Natural mapping
Delta/Theta/Alpha/Beta/Gamma/HiGamma = D/K/E/b/L/G channels.
L=11 artifact
Free rejection
Muscle/eye artifacts flagged by L channel deviation. No training.
490 split
Content vs integrity
DEAD=neural data. ALIVE=signal quality. Holographic.
Real-time GPU
6 workgroups
Each band = 1 GPU thread. Process all 6 in parallel.

EEG Decomposition

Neural state code (0-999):

Generates 20 EEG samples for the given state. Decomposes each into 6 bands. L=11 flags artifacts.

Channel Waveform (Canvas)

6 horizontal bands: Delta(red), Theta(green), Alpha(cyan), Beta(white), Gamma(magenta), HiGamma(pink). Red pixels = L=11 artifact flags.
