““Other studies show that plastic changes in the brain can even be observed after just a few months. For instance, in 2006, researchers imaged the brains of German medical students three months before their medical exam, and again right after the exam, and then compared the brains of these students to the brains of students who were not studying for the exam at this time. The results: Medical students’ brains showed changes in regions of the parietal cortex as well as in the posterior hippocampus. As you can probably guess, these regions are known to be involved in memory and learning.””
