What is Artificial Intelligence?

Natural brain activities have been measured to show changes in the learning curves of the brain connection during particular activities.

Researchers from Washington University School of Medicine in St. Louis and the University of Chieti, Italy, have recently reported in their study that the brain's spontaneous activity is but organized in patterns of correlated activity. Furthermore, this study have shown that the learning behaviors have caused considerable changes in the spontaneous brain patterns.

The researchers performed an experiment on 14 volunteers who were brain-scanned through fMRI as they rested. Then, they were scanned again as they went through the activities involving watching displays of MRI patterns with an inverted 'T' in an area of the screen. The activities lasted for five to seven days.

After the experiment, the subjects were scanned for the third time while they did nothing.

fMRI scan results have shown that at the start of the experiment, while the subjects rested, the spontaneous brain activities in the two parts of the brain were weakly correlated with the two regions involved in the activities.

Also, scans showed that either of these two is active during the tests, meaning they do not work simultaneously which lead to the conclusion that "disruption of spontaneous correlated activity may be a common mechanism through which brain function abnormalities manifest in a number of neurological, psychiatric or developmental conditions," Corbetta says.
