Using a new test called the electroencephalograph, the study measured the electrical activity in the brain, and sought to deduce character from the squiggles.
A team led by Dr Lakhmir Chawla used an electroencephalograph (EEG), a device that measures brain activity, in seven terminally ill people to provide pain-relieving sedation.
In 2007 the duo built a body-heat powered electroencephalograph device that monitored brain activity.
The long history of the brain's depiction, from the first raw sketches of antiquity, through early electroencephalograph EEG recordings, to the abstract art of modern-day scanners is charted in the newly published Portraits of the Mind – from which a selection of images are shown here – by Carl Schoonover, a doctoral student in neurobiology at Columbia University in New York.
For the new study, researchers used an electroencephalograph (EEG) to measure brain function of 26 children while they watched images flashing on a computer.
During the experiment, an electroencephalograph monitored the part of the brain that is known to detect conflicts between a habitual response (in this case -- tapping a key) and a more appropriate response (not tapping a key).
During the test, an electroencephalograph recorded activity in the anterior cingulated cortex, a part of the brain involved with the process of stopping the brain from following a well-worn path when something has changed (stopping you from driving your car into an unexpected “Road Closed” sign on your way home from work, for example).
The electroencephalograph detects three distinct patterns of electrical activity -- waking ...
They are, instead, electrical signals that are easily picked up by an electroencephalograph (EEG).
The electroencephalograph EEG brain wave records of both subjects were then synchronized and examined for “normal” potentials evoked in the stimulated subject and “transferred” potentials in the non-stimulated subject.
