I wanted to share this photo again as I particularly like this mediation of my artwork ‘The Phrontesterion’ – it captures the essence of biofeedback / neurofeedback in a digitally enabled and augmented portraiture medium, with a nod to the classic genres in painting, sculpture and observation / witness / patient ( by the next participant waiting in the wings ) We the audience witness the fleeting changes from Beta, Alpha and Theta into Hypnagogic brainwaves undulate on a screen, as the percipient, the solo audience member being monitored engages in a discrete interaction with the sound of their own thoughts, frontal lobe decisions and potential surreal reveries sonified !
I find the whole experience quite intimate, and I interview each person afterwards. This was in The East Wing of The Royal Academy in 2015 during ‘Lates’, one of my favourite evenings ever as an artist.
See and head the outcomes here as 10 minutes is compressed to 1 minute 43 seconds, all sounds are triggered by EEG and all Entoptic and Phosphene ephemeral visuals are experienced by the percipient in the dentist chair, behind closed eyelids.
The artwork involves a brainwave monitor, so all the sounds heard are modulated and controlled via the participant – their EEG signal is being recorded in realtime and output as dynamic changes and interaction within a sonic score. A sonification we can hear manifests, as do ‘Entoptic’ patterns, phosphenes and many ‘non-linear narratives’ making a unique phenomenal artwork for each participant (their eyes are closed, and they are wearing headphones in a dentist chair). The Phrontesterion is driven by their brain’s response to a Theta wave (4-8 Hz) entrainment protocol by lights (PandoraStar & Dreamachine), in return they receive access to subconscious idling, reveries and tranquility.
The video was captured by Go Pro and shows the 10 minute experience condensed to one minute.. the following visual analysis is the EEG of the participant made using IBVA software and captured using a 2 channel Brainmachine monitor ( http://www.brainmachine.co.uk) all the sounds are made from the EEG controlling the score, custom Brain Switch Audio Unit plugins are in the library to enable this for each frequency bandwidth from the Left and Right sides of the frontal region ( FP1 and FP2 )
