What you'll learn

✓ Perform Neuroscore assessment to detect acute neurological deficits
✓ Conduct beam-balance and beam-walking tests to evaluate motor function
✓ Administer working memory water maze to assess cognitive impairment
✓ Interpret behavioral results to localize brain injury damage

Protocol

Biopharma Insights The goal of the behavioral tests presented here is to detect functional deficits in rats after traumatic brain injury. Four specific tests are presented that detect deficits in behaviors to reflect the damage to specific brain areas at times extending to one year after injury.

Difficulty

advanced

Total time

~45–60 min per rat per testing session; repeated over multiple weeks to months post-injury

Model organism

Rat (species not specified)

Steps

Perform Neuroscore training and testing protocol

Train and test rats using the Neuroscore assessment to detect acute neurological deficits immediately and shortly after traumatic brain injury. This standardized scoring system reflects overall neurological function.

▶ 01:20

Conduct beam-balance testing for motor assessment

Evaluate postural stability and balance by having rats maintain position on a narrow beam. This test detects motor coordination deficits resulting from brain injury.

▶ 03:10

Train and test beam-walking task performance

Train rats to traverse a narrow beam and assess their ability to cross without falling. Beam-walking measures motor function, coordination, and fine motor control impairment.

▶ 03:35

Administer working memory water maze test

Place rats in a water maze to assess spatial working memory and cognitive function. This test detects hippocampal and cortical damage affecting learning and memory.

▶ 04:41

Analyze and interpret behavioral test results

Evaluate performance across all four behavioral tests to correlate functional deficits with specific brain regions damaged. Results extend assessment up to one year post-injury.
