Dr. Vance, a neuropsychologist, is working with an individual, Marcus, who exhibits impulsive aggressive outbursts. Dr. Vance used functional neuroimaging (fMRI) to measure Marcus's neural activation during various simulated social scenarios, calculating a 'Neural Risk Index' from 1 to 10 for each scenario. A higher index indicates high amygdala activation relative to prefrontal cortex (PFC) activation, representing a greater neurological vulnerability to impulsive aggression. Marcus also kept a log of his real-life encounters with these scenarios over a three-week period. The results are shown in Table 3.
| Social Scenario | Neural Risk Index (1–10) | Occurrences in 3 weeks | Combined Risk Score |
|---|---|---|---|
| Perceived social rejection | 8 | 3 | 24 |
| Unresolved verbal conflict | 7 | 5 | 35 |
| Minor daily frustrations | 3 | 15 | 45 |
| Crowded/noisy environments | 5 | 8 | 40 |
| Total | 144 |
Describe how Dr. Vance could use this data and knowledge of brain structure (specifically the amygdala and prefrontal cortex) to advise Marcus on how to reduce his aggressive outbursts.
