Spring Connector FE Model: 0.31 mm/mm > strain in 1% spring connector elements |
Solid Element FE Model: 45.4 kPa > principal stress in 10% of surface brain elements |

Only 1 animal had an IHP score ≥ 25% in the posterior right region. Neither model predicted this single case and thus the sensitivity in this region was 0%.
