The Scottish National Gallery in Edinburgh, UK, is no stranger to unusual exhibitions and events, from Pin-Ups: Toulouse-Lautrec and the art of celebrity through to television comedian Phill Jupitus doodling pictures and telling jokes during his Sketch comedy sessions. Yet the arrival of Art on the brain—a touring project organised by Art Fund, a charity founded in 1903 to encourage the public to visit galleries and museums—perhaps marks the first time that visitors had been invited to wear an EEG headset while looking at the gallery’s artworks.
