Correlation of rCBF responses to 2-back working memory task among pre-frontal, parietal, and amygdala/hippocampal ROI’s.

Correlation Pre-Treatment
N=28		 Post-Treatment
N=28		 Significance
Of Difference
Pre-Frontal to Parietal .62* .94* P=.006
Pre-Frontal to Amygdala/Hippocampus .58* .84* P=.05
Parietal to Amygdala/Hippocampus .42* .80* P=.03

p< or =.01. Pre-treatment correlations show a similar pattern when participants with PET data only for the pre-treatment are added to the calculation (to yield n=43) and the significance of the pre-frontal to parietal correlation difference remains (p=.002). Removal of one participant with extreme change scores reduces the amygdala/hippocampus differences to a trend but the difference between prefrontal/parietal correlations pre and post remains significant (p=.04).
