Fig. 1. The figure shows corresponding boxplots and vertical histograms of rCBF values calculated separately for each region of interest and each participant. (A–D ) Summary plots for the top 20% blood flow data. (E–H ) Summary plots for the top 50% blood flow data. (I–L ) Summary plots for the top mean (average) blood flow data. The categorical axis (x-axis) shows experimental conditions. Regions of interest included were BA 1–4, BA 6 insular and cingulate cortex, amygdala, hippocampus, thalamus, and cerebellum. BA = Brodmann area; rCBF = regional cereral blood flow.
