Figure 2.

Representative Lassen occupancy plots for brivaracetam (BRV; red) and levetiracetam (LEV; blue) for two different doses. The values on the x‐axis represent regional V T values during baseline and on the y‐axis represent the difference between V T values during baseline and V T values postdrug. The SV2A occupancy was derived from the slope of the linear fit, that is, 50% for BRV (50 mg), 85% for BRV (200 mg), 52% for LEV (250 mg), and 84% for LEV (1500 mg)
