Table 4. Performance during rt-fMRI neural feedback training patterns of change in % volume of activation for specific ROIs across the first and last rt-fMRI neural training sessions.

PATTERN OF CHANGE IN % VOLUME OF ACTIVATION
I. Brain Region II. Decrease % Change (Subject number) III Increase % Change (Subject number) IV. No Change % activation (Subject number)
A. lesioned hemisphere, contralateral to the moving wrist
1. Primary Motor (BA 4ap)
 1.1. ‘Hand Knob’ sub-section of Primary Motor 29% (S3) 100% (S1) 100% (S2) 000% (S4)*
 1.2. Primary Motor sub-section, minus ‘Hand knob’ 10% (S2) 36% (S3) 06% (S4) 08% (S1)
2. Premotor (BA 6) 22% (S3) 5% (S1) 43% (S4) 48% (S2)
3. Sensory (BA 3ab) 10% (S1) 17% (S2) 51% (S3) 06% (S4)
B. Non-lesioned hemisphere, ipsilateral to the moving wrist
1. Primary Motor (BA 4ap)
 1.1. ‘Hand Knob’ sub-section of Primary Motor 62% (S1) 43% (S3) 100% (S2) 72% (S4)
 1.2. Primary Motor sub-section minus ‘Hand knob’ 41% (S1) 26% (S4) 12% (S2) 15% (S3)
2. Premotor (BA 6) 06% (S1) 07% (S4) 6% (S2) 10% (S3)
3. Sensory (BA 3ab) 19% (S1) 21% (S2) 41% (S4) 09% (S3)

*No Hand Knob region could be identified in the surviving tissue of S4’s lesioned hemisphere.
