Cross section of brain made with thousands of layers of gold leaf. Made by artist and neuroscientist Dr. Greg Dunn. Produced through a technique they call reflective microetching, the two cross-disciplinary artists track the neural choreography in the mind, creating brilliant images that glow with a metallic luminescence.The works depict a thin slice of the human brain at 22x the normal scale, each created through a combination of hand drawing, neuroscientific data, algorithmic simulation of neural circuitry, photolithography, strategic lighting design, and 1,750 sheets of 22k gold leaf.
