In their Untitled work (2008), that is reminiscent of the accuracy of a scientific experiment, Daniel Margulies and Chris Sharp make use of fMRI recordings to map brain activity in a subject who, after having meditated on a passage about knowledge and perception from Kant's Critique of Judgment, listens to Stravinsky's Rite of Spring. Their video shows a cross-section of a brain with changing patterns of colours in the areas that highlight during the experience. A copy of Kant's text as well as headphones channelling the music are available to viewers, who thus can perform and identify with the experiment by viewing on the screen an imagery that might be similarly going on in their own brains.

Split brain (2007)

The title refers to a "native", a cerebral angiogram which shows the whole brain including the arteries. Going native is also a metaphor for what it feels like to be seriously ill – and fighting for survival. Aldworth underwent a fMRI scan to get the images for the film which is in three sections. The first considers the fragility of personal identity: its dependency on the physical brain is suggested during the tap-dancing build-up to a brain haemorrhage. The second section looks at the physical brain after a stroke: as the doctors are working we see its structure as a series of patterned images ending with a spinning coin to suggest the randomness of illness. The final section asks us to think about our sense of self. The brain seems to be the seat of our personality, it contains all we are and know - our memories, feelings and thoughts. But what is their relationship to the brain's physical matter?
