Example Sentences

In the second season of the Netflix documentary Making a Murderer, Steven Avery, who is serving a life sentence for a brutal killing he says he did not commit, undergoes a “brain fingerprinting” exam, which uses an electrode-studded headset called an electroencephalogram, or EEG, to read his neural activity and translate it into waves rising and falling on a graph.

From The Guardian

“Brain fingerprinting could have provided the evidence we needed to bring the perpetrators to justice before they actually committed the crime.”

From The Guardian

“These people were already on watch lists,” Larry Farwell, the inventor of brain fingerprinting, told me.

From The Guardian

“Brain fingerprinting isn’t lie detection. It simply determines whether you are storing information.

That’s the concept of it, which is far superior to doing lie detection on the polygraph,” she said.

From The Guardian
