Radial Arm Water Maze
Objective: Assessment of spatial memory performance in mice following whole brain irradiation using the radial arm water maze
This is a Radial Arm Water Maze protocol using mouse as the model organism. The procedure involves 4 procedural steps, 3 equipment items. Extracted from a 2017 paper published in GeroScience.
Model and subjects
mouse • C56BL/6 • unknown • 3 months • not specified
Study window
~4 week study window
Core workflow
Whole Brain Irradiation Treatment • Spatial Memory Testing - Radial Arm Water Maze • Sensorimotor Coordination Testing - CatWalk
Primary readouts
- Spatial memory performance in radial arm water maze
- Sensorimotor coordination and gait parameters (regularity index and phase dispersion)
- Cerebromicrovascular function (whisker-stimulation-induced increases in cerebral blood flow)
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.

Whole Brain Irradiation Treatment
C56BL/6 mice at 3 months of age were subjected to fractionated whole brain irradiation protocol
Note: Fractionated protocol: 5 Gy twice weekly for 4 weeks. Control mice were also included for comparison.

Spatial Memory Testing - Radial Arm Water Maze
Mice were tested for spatial memory performance using the radial arm water maze
Note: Testing occurred at 3 to 6 months post-irradiation

Sensorimotor Coordination Testing - CatWalk
Mice were tested for sensorimotor coordination using computerized gait analysis
Note: Testing occurred at 3 to 6 months post-irradiation. Gait parameters measured included regularity index and phase dispersion.
