Follow-up related to the dual n-back test and its use in intelligence amplification:
Researchers at the Swedish medical university Karolinska Institutet have shown for the first time that the active training of the working memory brings about visible changes in the number of dopamine receptors in the human brain. The study, which is published in the journal Science, was conducted with the help of PET scanning and provides deeper insight into the complex interplay between cognition and the brain’s biological structure. […]
Professor Klingberg and his colleagues have previously shown that the working memory can be improved with a few weeks’ intensive training. Through a collaborative project conducted under the Stockholm Brain Institute, the researchers have now taken a step further and monitored the brain using Positron Emission Tomography (PET scans), and have confirmed that intensive brain training leads to a change in the number of dopamine D1 receptors in the cortex.
