re brain - behavior correlation

[Guest guest]

Is the date of this item 2004?

Was it published somewhere?

interesting - thanks for sharing!!

I thought this was interesting

Brain-behavior correlation in children depends on the

neuro-cognitive network

This study examined brain-behavior correlations in 12

children (9.3 to 11.7-year-olds) during a selective

attention task that required the visual search of a

conjunction of features and during a response

inhibition task that required the inhibition of a

pre-potent response during no-go blocks. We found that

the association between performance in these tasks and

brain activation as measured by functional magnetic

resonance imaging (fMRI) depended on the

neuro-cognitive network. Specifically, better

performance during the no-go task was associated with

greater activation in the response inhibition network

including the prefrontal cortex and basal ganglia. In

contrast, better performance during the visual search

task was associated with less activation in the

selective attention network including superior

parietal lobule and lateral premotor cortex. These

results show that the relation of performance to the

magnitude of neural activation is complex and may

display differential relationships based on the

cognitive domain, anatomical region and perhaps also

developmental stage.
