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.
