A new installation at The Franklin Institute in Philadelphia displays what happens in your brain—while you’re looking at it. The project comes from Greg Dunn and Brian Edwards, a neuroscientist and a physicist by training.
The idea behind the team’s new work, Self Reflected, is to foster an appreciation for the incredible complexity of the human brain. “You can read in a magazine or a textbook that the brain has 86 billion neurons in it, but it’s just totally meaningless,” says Dunn. He and Edwards confronted that scale head-on, hand-designing and painting five to ten versions of each kind of neuron that appeared in a single representative brain slice—150 cell types in all.
