After Images: Artistic Expressions of EEG Data Evoked by Optical Illusions

Abstract This paper delves into the fascinating relationship between neuroscience and art by creating visual and sonic artworks inspired by EEG data generated from optical illusions. By capturing the brain’s electrical activity in response to carefully chosen optical illusions, this research transforms intricate neural data into engaging artistic expressions. The project showcases how EEG, with its ability to capture brain activity in real time, can act as a medium for artistic creativity, offering a tangible representation of the brain’s dynamic processes during visual perception. Using a custom interface, the recorded EEG signals are converted into visual and sonic objects, enabling viewers to interact with the EEG data in an artistic setting. The resulting artworks provide a unique insight into how the brain interprets visual stimuli, highlighting the subjective nature of perception and the creative possibilities that neuroimaging technologies offer.
