Jon’s cerebrum is globally balanced at the macro level (+0.40% R>L), while his cerebellum shows meaningful right-lateralization (+6.33%). The pattern suggests a brain that is locally specialized rather than globally asymmetric.
| Structure | Asymmetry | Assessment |
|---|---|---|
| Cerebrum | +0.40% R>L | Balanced |
| Cerebellum | +6.33% R>L | Right-lateralized |
| Cerebellar GM | +8.37% R>L | Strongly right-lateralized |
| Region | Asymmetry | Functional Association |
|---|---|---|
| Sup. Frontal Gyrus (medial) | +26.84% R>L | Self-monitoring, meta-control |
| Occipital Fusiform | +23.23% R>L | Visual pattern recognition |
| Calcarine Cortex | +22.54% R>L | Primary visual processing |
| Frontal Pole | +20.58% R>L | Abstract reasoning, planning |
| Planum Temporale | −46.13% L>R | Auditory-language specialization |
| Opercular Inf. Frontal | −44.68% L>R | Speech production (Broca’s area) |
| Ant. Cingulate | −29.56% L>R | Conflict monitoring, effort allocation |
Jon’s profile shows globally typical anatomy with locally specialized networks. The rightward visual/occipital bias suggests strong spatial-visual modeling capability. The leftward cingulate pattern indicates a conflict-monitoring system that may be sensitive to context and benefit from externalized structure. The cerebellar right-lateralization (matching his CERES findings) supports prediction and automation loops.
Practical Implication: Jon’s brain appears optimized for visual-first thinking, high-level steering, and pattern synthesis. Executive function may be state-dependent—excellent at big-picture modeling but variable under low novelty or ambiguity. External scaffolding (visible task state, diagrams, structured workflows) isn’t compensating for weakness; it’s leveraging architectural strengths.
Caveat: This is structural volumetry from a single scan, not functional imaging. Large regional asymmetries (especially in opercular/orbital regions) can reflect normal anatomical variation and segmentation boundaries. Use as hypothesis-generating, not diagnostic.
