On January 1, 2008, Philip Grosser, choreographer and professor of dance at Temple University suffered a severe hemorrhagic stroke. While his motor skills remained intact, he suffered from aphasia, which meant he had to relearn speech and could no longer read. He can read now, but with great difficulty. It was in the hospital that Philip started drawing. Nerve Networks is the result of his search for a visual language to describe the new inner workings of his brain.
