General Health and Neurological Screening
Objective: Assessment of general health status and neurological function in mice as part of a behavioral test battery
This is a General Health and Neurological Screening protocol using mouse as the model organism. The procedure involves 5 procedural steps, 1 equipment items, 4 materials. Extracted from a 2016 paper published in Molecular Brain.
Model and subjects
mouse • C57BL/6J and genetically engineered mice with C57BL/6J genetic background • male • Not specified • Not specified • 1739
Study window
~1 day study window
Core workflow
Animal transport and acclimation • Housing conditions • General health and neurological screening
Primary readouts
- General health status assessment
- Neurological function evaluation
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.
Protocol Steps
Start here. The step list is optimized for running the experiment, with direct vendor links available inline when you need to source a cited item.
Animal transport and acclimation
Genetically engineered mice and wild-type control mice were transported from animal facilities of other laboratories or vendors to the laboratory
Note: Mice were housed in plastic cages with sterilized bedding under 12-hour light/dark cycle with lights on at 7:00 am

Housing conditions
Mice were housed in plastic cages with sterilized PaperClean Bedding under a 12-hour light/dark cycle with access to food and water ad libitum
Note: Housing density varied: 1.3% housed with 1 animal per cage, 2.3% with 2, 6.7% with 3, 80.1% with 4, 8.9% with 5, and 0.7% with 6 animals per cage at the beginning of test battery

General health and neurological screening
General health and neurological screening was performed as the first test in the behavioral test battery
Note: Testing was performed between 9:00 a.m. and 6:00 p.m. This test was performed first in the standard test battery order
View evidence from paper
“The mice were generally tested in the following order; general health and neurological screening, light/dark transition, open field, elevated plus maze”
Inter-test interval
Minimum interval maintained between consecutive behavioral tests
Note: More than 75% of mice were subjected to tests in accordance with the standard order, though some strains had tests omitted or reordered
View evidence from paper
“The interval between tests was at least 1 day.”
Apparatus cleaning and disinfection
All apparatus were cleaned between tests to prevent bias due to olfactory cues
Note: Cleaning was performed with super hypochlorous water and 70% ethanol

“After the tests, all apparatus were cleaned with super hypochlorous water and 70% ethanol to prevent a bias due to olfactory cues.”
