P-values of all directions of information flow estimated by Granger causality between ROI’s at different sampling rates from 1000 bootstrap iterations.

Each cell contains two p-values. The left p-value is for the left hemisphere (R condition) and the right p-value is for the right hemisphere (L condition). Only lower-triangular off-diagonal entries are listed. Upper-triangular off-diagonal entries can be calculated by (1–listed p-value). V: visual cortex; PCC: parietal cortex; PreM: pre-motor cortex; S: sensorimotor cortex; M: motor cortex. L: left hemisphere (R condition). R: right hemisphere (L condition).
