86 billion neurons. 100 trillion connections. what you are seeing is not a photograph or digital rendering. it is a depiction of the human brain made through reflective microetching, a technique by artist greg dunn with brian edwards, based on actual neuroanatomical data and diffusion spectral imaging, the same technology neuroscientists use to map living brains. the result functions as both art and science, a representation of neural architecture so accurate in its data and extraordinary in its execution that it blurs the line between the two. every branching filament represents the dendritic and axonal structure of the brain's communication network. 100 trillion synaptic connections forming, strengthening, and pruning across a lifetime of experience. the most complex structure known, contained in an organ weighing about 1.4 kilograms. the microetching gives it a holographic quality that shifts with light and angle, a brain that looks different every time you see it.
