when was the eeg developed
To this point, direct examination of brain activity as a window into the clientâs mind has remained elusive. But advances in the field of brain examination using electroencephalographs (EEGs) may be changing all that. The first EEG was developed in the 1920âs by the German psychiatrist Hans Berger. He developed it to test the biological electricity produced in the brain, and first used it during brain surgery performed in 1924 on a 17-year-old boy.
