summary
Claims a practical path from resting‑state MRI to intraoperative mapping of subcortical tracts, using preoperative default mode network nodes imported into the navigation system and direct stimulation during awake surgery. Tools: resting‑state fMRI, graph theory maps, navigation, electrical stimulation. Tests: a validated alternate uses task where stimulation abolishes creative responses, the Stroop test where cingulate stimulation causes conflict errors, and movie clips to probe emotional connectivity. One published method and patient vignettes show working but still experimental results.
