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). 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).
