Table 3.
rCBF estimates (mL/min/100mL) within the posterior parietal ROI for the different task conditions pre and post drug treatment. Means and standard errors are given; confidence intervals for 95% of the possible means may be approximated assuming normality by multiplying the standard error by + and − 2. There are no statistical differences between medication groups or pre-post treatment, see text.
