How Bad Helmets Gave Us a Map of Vision

The video discusses the Brodie helmet's design flaws and its impact on soldiers during early 20th-century wars. It highlights how bullet design changes led to more precise brain injuries, enabling breakthroughs in neuroscience. Tatsuji Inouye's work on mapping brain injuries to vision loss laid the groundwork for future research. Gordon Holmes and George Riddoch expanded on this, discovering functional partitioning in the brain, which processes different aspects of vision like motion, shape, and color. Despite modern technology, their early 20th-century brain maps remain remarkably accurate.
