OpenBCI – Gallery – Spectrograms

Gallery of brainwave samples using the OpenBCI Ganglion.

KOB was able to make changes to the settings of EEGRUNT to analyze two OpenBCI Ganglion readings, and was kind enough to send me the results.

Spectrogram software is EEGRUNT  by Isa at Autodidacts.io

In the first sample, my test subject DH laughed and talked while watching a video.  Because of the laughing and talking there is presumably more noise due to facial movement.

In the second sample, my test subject DH read while doing his best to keep is face immobile. Because of the less facial motion, there is presumably less noise due to facial movement.
