Effects of heroin on brain perfusion in contrast to placebo.

Altered regional perfusion in heroin in comparison to placebo condition.
<p>A) Relative hypo- (blue) and hyperperfusion (red) in heroin condition projected on an inflated brain (threshold: p<0.05). Hyperperfusion was not significant. B) Significant hypoperfusion (blue) in heroin condition (threshold: p<0.01; FEW corrected p<0.05). The z coordinate shows the position of each slice in reference to the Talairach atlas (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0071461#pone-0071461-t003" target="_blank">Table 3</a>). The medial prefrontal cortex, the anterior cingulate cortex, and the insular cortex are shown in different colors, in order to clarify the spatial relationship to the significant clusters.</p
