Functional recruitment of regions during different encoding loads.

<p>Event averaged time courses with standard error bars (top) and spatial regions correlated to beta estimates (bottom) for all three probe sizes (4, 5 and 6) for both the control and schizophrenia groups within the left-prefrontal-parietal encoding circuit. Regression results are thresholded at p<0.01 uncorrected level. Regions are color coded as follows. Red – load 4; Green – load 5 and Blue – load 6. Note, the absence of fMRI response in the posterior parietal and increased right PFC recruitment in the schizophrenia group (compared to controls): during lower loads suggesting a load-dependent functional disconnection of this neural network.
