Table A1.
Number of subjects exhibiting each kind of behavior, according to the lesion extent of the anterior cingulate (AC), orbitofrontal (OF), and prelimbic (PL) cortices.
| Lesion size | AC | OF | PL | ||||||
|---|---|---|---|---|---|---|---|---|---|
| 1 | 2 | 3 | 1 | 2 | 3 | 1 | 2 | 3 | |
| Good decision-makers | 1 | 1 | 1 | 1 | 1 | 1 | 1 | ||
| Poor decision-makers | 1 | 1 | 1 | 1 | |||||
| Undecided behavior | 1 | 1 | 1 | 1 | 1 | 3 | |||
| Inflexible behavior | 1 | 2 | 2 | 2 | 2 | 1 | 4 | ||
| Delayed good decision-makers | 2 | 2 | 1 | 1 | |||||
| Total number of subject for each lesion size | 5 | 6 | 3 | 3 | 6 | 3 | 3 | 6 | 4 |
Three extents of lesion size were chosen arbitrarily: the overall cerebral structure was lesioned (between 80 and 100%) on every histological section (degree 3); the structure was not completely lesioned on some histological sections (from 60 to 80%; degree 2); and the structure was significantly but not completely lesioned (from 50 to 60%) in most of the histological sections (degree 1).
