Summary of Animal Models Used in Work Assessing sleep–wake Disturbances After TBI.
Model | Type of injury | Strengths | Weaknesses | Species |
---|---|---|---|---|
FPI | · Mixed global/focal insult | · Very common model used | · Requires craniotomy | · Mouse, 100,164,169–171 Rat 165 |
· Midline or lateral | · Highly reproducible · Mild regarded as the most translation model of TBI | · Does not replicate clinical TBI in terms of skull fracture · Limited mechanical control over neurological insult | ||
CCI | · Predominantly focal | · Single or repetitive insults | · Requires craniotomy | · Mouse, 155,167,168,173 Piglet 172 |
· Highly reproducible | ||||
· Severity of neurological insult easily controlled | ||||
Weight Drop | · Mixed global/focal insult | · Representative of human conditions· Does not require craniotomy | · Not highly reproducible· High mortality without post-injury 100% O2 ventilation | · Mouse, 157 Rat 158,159 |
Abbreviations: FPI, fluid percussion injury; CCI, controlled cortical impact injury; TBI, traumatic brain injury.
