Functional magnetic resonance imaging ( fMRI) has reportedly yielded another insight into how the human brain functions. fMRI is a non-invasive imaging technique that exploits a particular modern instrument's ability to sense the magnetic properties of water in order to detect changes in the rate that tissue is using oxygen. How rapidly a tissue uses oxygen is a good indicator of how much work it is doing. So, when using fMRI to study a human doing mental tasks, a scientist can tell which areas of the brain are active (functioning).
Using the fMRI technique in a controlled study, French researchers at Université Pierre et Marie Curie and Ecole Normale Supérieure have reportedly discovered that Broca's area (located near the left temple), along with its companion area on the right side, is involved in more than just organizing speech - it also organizes (plans) many other things. This planning ability is one of the major things that distinguishes human intelligence from that of other species.
