Cognitive Training (Cogmed) Changes the Brain More Than We Thought

Cognitive Training Can Alter Biochemistry Of The Brain (Science Daily)

– “Researchers at the Swedish medical university Karolinska Institute 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.”

– “”Brain biochemistry doesn’t just underpin our mental activity; our mental activity and thinking process can also affect the biochemistry,” says Professor Torkel Klingberg, who led the study.”

– “Changes in the number of dopamine receptors in a person doesn’t give us the key to poor memory,” says Professor Lars Farde, one of the researchers who took part in the study. “We also have to ask if the differences could have been caused by a lack of memory training or other environmental factors. Maybe we’ll be able to find new, more effective treatments that combine medication and cognitive training, in which case we’re in extremely interesting territory.”

Comment:  couldn’t agree more with “Maybe we’ll be able to find new, more effective treatments that combine medication and cognitive training, in which case we’re in extremely interesting territory.” This study adds a very important angle to the growing literature on working memory training, showing a more fundamental, structural impact, that once thought (such as the well-known effect that “cells that fire together wire together”). The computerized cognitive program used in the study was Cogmed working memory training.
