Resting state fcMRI in pre-operative brain mapping: (A) Structural MRI scan showing a mass in the right frontal cortex. Green circle represents the location of ipsilateral hand response to intra-operative cortical stimulation. (B) Task-related mapping showing activity within the sensorimotor network but also small responses in parietal cortex that are seemingly unrelated to motor function or sensation. (C) Resting-state correlation mapping showing that the sensorimotor network is largely unaffected by the tumor anterior to the central sulcus. Seed region is shown (blue circle). All images are displayed left-on-left. Adapted with permission from (Zhang et al., 2009a).
