Effect of kernel size on true positive rates for various activation sizes with simulated data. The statistical threshold was held constant at z = 3. A range of kernel sizes was used from 0.05 to 0.50. CNRs used are 0.20, 0.40, 0.60, and 0.80. A: 20 × 20 activation size. B: 10 × 10 activation size. C: 2 × 2 activation size.
