Water Maze
Objective: Assessment of spatial navigation and memory abilities in rats with selective hippocampal lesions
This is a Water Maze protocol using rat as the model organism. The procedure involves 3 procedural steps, 3 equipment items. Extracted from a 2002 paper published in Proceedings of the National Academy of Sciences.
Model and subjects
rat • Not specified • unknown • Not specified • Not specified
Study window
Estimated timing pending
Core workflow
Elevated plus-maze testing • Brightly lit chamber confinement • Spatial navigation testing
Primary readouts
- Avoidance of open arms in elevated plus-maze
- Neuroendocrine stress responses (corticosterone levels)
- Spatial navigation performance in water maze
- Contextual fear conditioning
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.
Use the page like this
- Work through the protocol steps in order and use the inline vendor chips only when you need to source or verify an item.
- Jump to Experimental Context for readouts, data shape, and analysis flow before planning downstream analysis.

Elevated plus-maze testing
Rats with selective hippocampal lesions were tested in an elevated plus-maze to assess fear-related behavior and avoidance of open arms
Note: Rats with selective hippocampal lesions failed to avoid open arms, indicating reduced fear expression

Brightly lit chamber confinement
Rats were confined to a brightly lit chamber to assess neuroendocrine stress responses
Note: Rats with selective hippocampal lesions had decreased neuroendocrine stress responses

Spatial navigation testing
Rats were tested in a water maze to assess spatial navigation and memory abilities
Note: Ventral hippocampal lesions failed to impair spatial navigation performance
