Figure 5. Degree of functional laterality for motor-related regions of interest.

Figure 5

The laterality index (LI) for each region of interest is plotted for both controls (lined) and cocaine users (solid). A positive LI means that activity is lateralized to the left hemisphere, while a negative LI indicates right sided laterality. Brain regions with significant between group differences are indicated with asterisks (* p<0.05).
