- Berger attached silver wires to the scalps of his patients and recorded the voltage changes on photographic paper. He discovered the "alpha wave," which occurs when a person is awake with their eyes closed.
- At first, the medical community didn't believe his results, assuming the electrical noise was just artifact interference from the skin or surrounding environment.
- This was the absolute foundational step in neurotechnology, proving that human consciousness has a physical, electrical footprint that can be measured by machines.
