significant after Bonferroni adjustment (critical p=.007). Coefficients are standardized regression coefficients, and can be interpreted as correlations. Sex is coded as 1= man and 2 = women. Group 1=experimental and 2=control; Hypertension 0=normotensive and 1=hypertensive; L – level, C – change.
Abbreviations: HC – hippocampus, DLPFC – dorsolateral prefrontal cortex, OF – orbitofrontal cortex, VC – primary visual (pericalcarine) cortex, CD – caudate nucleus, CB – cerebellum, FW – prefrontal white matter.
