Effect of neurofeedback training on neural substrates of selective attention in children with ADHD
Another new study, this one using neuro-imaging out of the University of Montreal, shows that neurofeedback is very likely highly effective in helping children with attention deficit hyperactivity (ADHD) disorder.
Given the fact that neuroimaging studies show abnormal functioning of
the anterior cingulate cortex in those with ADHD (attention deficit
hyperactivity disorder) during tasks involving selective attention,
researchers at the University of Montreal conducted a randomized,
controlled pilot study to examine whether neurofeedback training (NFT)
could significantly improve cognitive functioning in children with
They devised a functional magnetic resonance imaging (fMRI) study to measure the effect of NFT on the neural substrates of selective attention in children with AD/HD. Twenty AD/HD children, who were not taking any psychostimulant drugs participated to the study.
At Time 1, for both groups, the Counting Stroop task was associated with significant loci of activation in the left superior parietal lobule. No activation was noted in the anterior cingulate cortex. At Time 2, for both groups, the Counting Stroop task was still associated with significant activation of the left superior parietal lobule. This time, however, for the intervention group only there was a significant activation of the right ACC. These results suggest that in AD/HD children, NFT has the capacity to normalize the functioning of the anterior cingulate cortex, the key neural substrate of selective attention.
