Stress Response Measurement
Objective: Measurement of neuroendocrine stress responses including corticosterone levels during confinement to a brightly lit chamber in rats with and without hippocampal lesions
This is a Stress Response Measurement protocol using rat as the model organism. The procedure involves 3 procedural steps, 2 equipment items. Extracted from a 2002 paper published in Proceedings of the National Academy of Sciences.

- Neuroendocrine stress response magnitude
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.

Confinement to brightly lit chamber
Rats are confined to a brightly lit chamber to induce stress response
Note: This procedure is used to measure neuroendocrine stress responses

Measurement of corticosterone levels
Neuroendocrine stress responses are measured, specifically corticosterone levels
Note: Corticosterone is a stress hormone measured as an indicator of neuroendocrine response

Elevated plus-maze testing
Rats are tested on an elevated plus-maze to assess fear-related avoidance behavior
Note: Open arm avoidance is measured as an indicator of unconditioned fear
