The First Human EEG Makes Brain Signals Non-Invasive
Hans Berger recorded electrical activity from a human brain, creating electroencephalography as a practical window into neural rhythms.
EEG moved brain recording from exposed animal cortex to electrodes placed on or near the human scalp. Its signals were safe and repeatable but spatially coarse, creating a tradeoff that still shapes non-invasive brain-computer interfaces.
