03_EEG DATA VISUALIZATION

EEG Data Visualization Tests
2020

Exploration



Early explorations of the EEG raw data data reading and transformation in Grasshopper, for extraction of categorized brain waves.
The process entailed several steps:
1. reading of recorded raw EEG files from 22 possible electrodes
2. tranforming data using Fast-Fourier Transformation (FFT) for binning frequencies and creating spectrum analisys graphs
3. creating bands for visualizing alpha, beta, delta and gamma waves and their relative powers.

These visualizations were an insteresting and accidental result of directly plotting FFT data into X,Y coordinates and creating delauney meshes
