Cerebral regions showing significantly different power of response to the non-word rhyming task and the letter case judgment task between the very preterm group and the control group
| Number of voxels | Talairach coordinates (mm) | Maximum difference in FPQ | |||
|---|---|---|---|---|---|
| x | y | z | |||
| x, y, and z refer to the stereotactic coordinates36 of the voxel within each cluster with the largest fundamental power quotient (FPQ, reflecting the significance of periodic change). The reference point for the coordinates is the junction of the vertical anterior commissural line and the intercommissural line. The reference plane is the bicommissural plane. x refers to millimetres left (−) and right of the reference point, y to millimetres anterior and posterior (−) to the reference point, and z to planes above and below (−) the reference plane. | |||||
