A new research found that it is actually not a specific region of the brain or the system of processes that are happening on the brain that determines whether a person is smart or not.

Instead, researchers found that it is in fact the connections between specific areas in the brain that determine the intelligence of a person and to some extent, his status in life.

According to the study’s lead author, Jan Glascher, general intelligence lies on the connections between the gray matter and the white or the fibers connecting the neurons. It also lies between the frontal and parietal parts of the brain.

The results were not really a surprise and it just confirmed what scientists believed that general intelligence is a result of the communication between parts of the brain.

General intelligence is an abstract idea discovered in 1904 by Charles Spearman and until now, it still brings forth controversy in the psychological community.

General intelligence is the idea that if you are smart, then you have to be smart in all subjects. This definition alone has been disputed by many psychologists through time since its inception.

For the study, the researchers studied 241 patients with some degree of brain lesion. The lesions were diagrammed and the patients were made to take IQ tests.

The results of the test were put side by side with the data of the parts of the brain of the patients that were damaged. The scientists were then able to devise a map that was based on the findings. They were able to pinpoint which connections make up general intelligence.

In a previous study done by the same researchers, they were able to find out that this same network in the brain plays a vital for working memory.

The study is published in this week’s issue of the Proceedings of the National Academy of Sciences.
