What would you ask about all this stuff?
Offbeat Q & A with John C. Lilly
during the making of the JCL Homepage
Q: I read about your invention, the 25-channel Bavotron in 1950, but I wasn't sure what it was."
JCL: It was the first device to measure the electrical pulses of the cerebral cortex. Now there are such devices using 400 channels"
Q: Then it was like the first EEG?
JCL: No. EEGs measure the electricity of the brain at the scalp. The Bavotron measured them at the actual cortex.
