Neurological Severity Score
Objective: Evaluation of neurological deficits and functional recovery after traumatic brain injury using neurological severity score assessment
This is a Neurological Severity Score protocol using rat as the model organism. The procedure involves 8 procedural steps, 2 equipment items, 2 materials. Extracted from a 2015 paper published in Journal of neurosurgery.
Model and subjects
rat • Wistar • 8
Study window
~5 week study window
Core workflow
Traumatic brain injury induction • Treatment administration • Behavioral testing - Morris water maze
Primary readouts
- Cognitive functional recovery (Morris water maze)
- Sensorimotor functional recovery (Morris water maze and footfault test)
- Neurological deficits (neurological severity score)
- Lesion volume
Key equipment and reagents
Use this page as an execution guide, then fall back to the source paper whenever you need exact exclusions, dosing details, or assay-specific caveats.
Confirm first
- Verify the animal model, intervention setup, and collection timepoints against the source paper.
- Check that every direct vendor link matches the exact specification your lab plans to run.

Traumatic brain injury induction
Wistar rats were subjected to TBI
Note: Baseline procedure before treatment

“Wistar rats were subjected to TBI”
Treatment administration
Tail vein injection of either 100 µg protein of exosomes derived from MSCs or equal volume of vehicle phosphate-buffered saline
Note: Two treatment groups: exosome-treated (n=8) and vehicle control (n=8)

Immunohistochemical analysis
Immunohistochemical analyses performed to measure neurovascular remodeling (angiogenesis and neurogenesis) and neuroinflammation
