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.

Protocol Steps

Pool setup
Set up a black cylindrical pool divided into four quadrants (I-IV) with a concealed circular platform placed in quadrant I's center, 1 cm under the water surface. Position fixed visual cues around the pool and render water opaque with white dye.

“The tank was notionally separated into four quadrants (I–IV). A concealed circular platform (10 cm diameter) was placed 1 cm under the water surface in quadrant I's center”
Navigation phase
Conduct navigation training for 5 successive days with 4 trials daily and 1-hour intervals between trials. Record escape latency (time from entering water at varying start locations to finding the platform). Analyze the mean daily value from four trials.

“Mice received 4 trials daily for 5 successive days (1‐h intervals between trials). Escape latency (time from entering water at varying start locations to finding the platform) was recorded”
Spatial probe phase
On Day 6, withdraw the platform and release mice from the quadrant opposite the original platform site. Track their swimming path over 60 seconds and quantify time spent in the target quadrant and platform crossings.

“On Day 6, the platform was withdrawn. Mice were released from the quadrant opposite the original platform site. Their swimming path over 60 s was tracked”
