Using a technique called magneto-encephalography that measures brain signals, the Oxford researchers found that a baby's face can seize our attention in milliseconds, activating an unusual mental organ called the fusiform gyrus that responds to human faces.
By combining different measures of brain activity -- positron emission tomography, functional magnetic resonance imaging and electro-encephalography -- scientists for the first time can see how aging brain regions, designed to work in unison like the interlocking innards of an expensive watch, fail to mesh swiftly and smoothly.
The scientists used a technique known as magnetic encephalography MEG — the fastest of all scanner methods — to measure the minute magnetic fields around the brain and identify regions that are active during the second or so it takes for a person to make their shopping choice.
Moniz's main interests were evidently encephalography, and cerebral arteriography.
Extensive special examinations, such as contrast encephalography and pneumaencephalography, that is, X-ray examination with a contrast medium in the vessels, and filling the brain cavities with air following lumbar puncture, provide very valuable information, but nevertheless indirectly.

The mentation pictures we got by encephalography compare very favorably with those of any human child of ten or twelve years old, and so does their learning and puzzle-solving ability.
