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.
