Table 2 Functional imaging characteristics and postoperative motor function

From: Plasticity of motor function and surgical outcomes in patients with cerebral arteriovenous malformation involving primary motor area: insight from fMRI and DTI

Patient No. BOLD activation areas CST derived from Stimulation positive sites Post-operative motor function
  Contralesional hemisphere Ipsilesional hemisphere Contralesional hemisphere Ipsilesional hemisphere cortex subcortex 2nd day 7th day 3rd month 6th month
1 None PMA*, SA None PMA, SA Behind lesion Behind lesion III IV V V
2 None PMA, SMA* None SMA None Before lesion IV IV+ V V
3 None PMA* None PMA In lesion In lesion I I III IV

5 SPL, PMA* SA none SA Behind lesion Behind lesion III III IV IV
  1. BOLD activation areas: BOLD activation areas elicited by contralesional hand or foot movement. Stimulation positive sites: Positive sites of electrical stimulation. Post-operative motor deficit: muscle strength of hand and/or foot contralateral to lesion hemisphere
  2. PMA primary motor area, SMA sensorimotor area, SA sensory area, SPL superior parietal lobule, AMA anterior motor area, U: unavailable
  3. * labeled the peak motor activity point
