Working memory training changes the brain

By Gregory Kellett, a cognitive neuroscience researcher at SFSU and science writer for Lumos Labs .

It seems that working memory training may work by physically altering the brain. Stockholm Brain Institute researchers put healthy people through working memory exercises for 35 minutes per day over a period of 5 weeks. Changes in dopamine receptor density were measured with positron emission tomography (PET) before and after the training.

Following working memory training, they found:

  • An increase in the density of dopamine receptors.
  • An improvement in working memory performance.
The neurotransmitter dopamine plays a central role in working memory. This research implies that improving working memory performance through several weeks of training might work by increasing the quantity of dopamine receptors in the brain
