BCIs have deep roots. In the 18th century Luigi Galvani discovered the role of electricity in nerve activity when he found that applying voltage could cause a dead frog's legs to twitch. In the 1920s Hans Berger used electroencephalography to record human brain waves. In the 1960s Jose Delgado theatrically used-a brain implant to stop a charging bull in its tracks. One of the field's father figures is still hard at work in the lab.
