Brain Computer Interface for audio neural Feedback

Audio Neural Feedback

Explaining the concept of listening to brainwaves through Brain-Computer-Interfaces in my workshop class conducted at MIT Media Lab. I am wearing Muse BCI on my forehead.

Decomposing EEG

Visualizing the power spectral sub bands of EEG and their frequencies.

Power Spectral Densities

Delineating alpha, beta, gamma, theta and delta power spectral bands of electroencephalogram.

Listening to my brain Live

Demonstrating audio neural feedback through a wearable EEG and a live smartphone application.

Listening to the brain in real-time
I developed an android application for real-time audio feedback of the brain waves through wearable Brain Computer Interface.
The audio frequency output generated through the app is: k/alpha.
(k is the amplification constant, alpha is the power spectral density value of the EEG calculated)
Since the alpha spectral band has the highest power when calm, the audio frequency lowers as you become come and less strained and frequency increases with the decrease in alpha band power.
