Jena, Germany, 1924: Working in near-isolation and with painstaking tediousness, the psychiatrist Hans Berger observes rhythmic electrical activity from the scalp of human subjects. He is convinced the activity arises from within the brain and coins the term “electroencephalogram.”It is 10 years before the scientific community accepts Berger’s work, birthing the field of electroencephalography, or EEG for short.Today, the electroencephalogram – also abbreviated as EEG – is widely known as a medical test measuring brain electrical activity that’s used on patients who have, or are suspected to have, neurological disorders. The EEG provides a window into the living brain, with a continuous electrical readout of what is happening inside our heads. The procedure may be short, often just a 30-minute recording. But for patients monitored for diagnosis or treatment of brain disease, it can be continued for much longer – days or even weeks.As a neurologist specializing in epilepsy, I use EEG on a daily basis.

Berger’s interest in brain electricity was not to combat disease, though that was his day job as a physician, but to find a biological basis for his belief in telepathy.
