Joe Hardy reports on a study by Backman et al (2011) in Science, where from the authors report:
Updating of working memory has been associated with striato-frontal brain regions and phasic dopaminergic neurotransmission. We assessed raclopride binding to striatal dopamine (DA) D2 receptors during a letter-updating task and a control condition before and after 5 weeks of updating training. Results showed that updating affected DA activity before training and that training further increased striatal DA release during updating. These findings highlight the pivotal role of transient neural processes associated with D2 receptor activity in working memory.
Joe Hardy goes on to claim:
This result shows that cognitive training with exercises similar to those on Lumosity can change the way the brain works at a fundamental chemical level. Indeed, we’ve known for several years that the right kind of cognitive training can enhance brain functions like working memory.
- Is it true that cognitive training enhances dopamine release ?
- Are there any studies that disprove this ?
