The Elevated Plus Maze (EPM) is a widely used behavioral assay for measuring anxiety-like behavior in laboratory rodents. The apparatus consists of four arms arranged in a plus configuration at 90 degrees, with two open arms and two enclosed arms elevated above the ground. This design exploits the natural conflict between rodents' innate exploratory drive and their aversion to open, elevated spaces.
Constructed from non-reflective matted acrylic, the maze is available in species-specific dimensions for mice and rats, with customizable features including door options, wall height modifications, and raised edge lips. The apparatus enables quantitative assessment of anxiety-related behaviors through measurement of time spent in open versus closed arms, arm entries, and ethological parameters such as risk assessment behaviors and locomotor activity patterns.
How It Works
The elevated plus maze operates on the principle of approach-avoidance conflict, exploiting rodents' natural behavioral tendencies. Animals experience a conflict between their innate drive to explore novel environments and their aversion to open, elevated spaces that represent potential danger. The maze's elevation (61cm above ground) and open arm design create an anxiogenic environment that activates the animal's fear response system.
During testing, animals are placed in the central platform and allowed to freely explore all four arms for a defined period, typically 5-10 minutes. Anxiety-like behavior is quantified through multiple parameters including percentage of time spent in open arms, number of open arm entries, total arm entries (locomotor activity), and ethological measures such as stretch-attend postures, head dips, and defecation. Higher anxiety levels correlate with reduced open arm exploration and increased closed arm preference.
The non-reflective matted surface prevents visual artifacts that could influence behavior, while the ethanol-cleanable acrylic construction ensures consistent testing conditions between subjects. Optional modifications including doors, variable wall heights, and raised edge lips allow researchers to adjust the apparatus for specific experimental requirements and species-appropriate testing parameters.

Practical Tips
Calibration
Verify arm dimensions and platform level using precision measuring tools before initial use and periodically thereafter.
Why: Dimensional accuracy affects the anxiogenic stimulus strength and behavioral measurement validity.
Maintenance
Inspect arm joints and support connections regularly, tightening hardware as needed to prevent movement during testing.
Why: Apparatus stability prevents vibrations that could influence animal behavior and measurement accuracy.
Best Practices
Habituate animals to the testing room environment for 30-60 minutes before EPM testing to minimize handling stress effects.
Why: Reduced stress from novel environments allows cleaner measurement of anxiety-specific behaviors rather than general stress responses.
Data Quality
Record both traditional parameters (time in open arms, entries) and ethological measures (stretch-attend postures, head dips) for comprehensive behavioral analysis.
Why: Ethological parameters provide additional sensitivity to detect subtle behavioral changes and validate anxiety-related interpretations.
Troubleshooting
If animals consistently avoid the central platform, reduce lighting intensity or check for vibrations from building systems.
Why: Environmental factors can overshadow the maze's anxiogenic properties and reduce the validity of behavioral measurements.
Safety
Consider raised edge lip modifications when testing animals with motor impairments or when conducting extended duration protocols.
Why: The 0.5-1cm safety barrier prevents falls while maintaining the open arm's anxiogenic properties for valid behavioral measurement.
Best Practices
Test animals during their active phase and maintain consistent timing across experimental groups.
Why: Circadian rhythms affect anxiety-related behaviors and locomotor activity levels in rodents.
Maintenance
Store the disassembled apparatus in a dry environment to prevent acrylic clouding and ensure longevity.
Why: Proper storage maintains the non-reflective surface properties essential for consistent behavioral testing conditions.

Introduction
The Elevated Plus Maze was introduced by Pellow et al. (1985) 1 as an unconditioned model of anxiety, building on earlier observations by Montgomery (1955) 2 that rats avoid open and elevated spaces. Pellow demonstrated that the open-arm avoidance response is reversed by classical anxiolytic compounds and exaggerated by anxiogenic challenges, establishing pharmacological validity for the paradigm.
Within a decade the EPM became the most widely-used anxiety screen in preclinical neuroscience. By 2010, over 6,000 published studies had used the apparatus. 1 Its appeal: the test is short (5 minutes per animal), requires no training or food deprivation, and produces a robust between-group effect size with N=8-12 per group. 2
The EPM is now the canonical first-pass screen for anxiety-like behavior in rodents and the back-translational bridge between human anxiolytic literature and preclinical mechanism work. Its limitations and confound profile, addressed in Discussion §4, are well-characterized. 12
§ 2
Methods
2.1 Procedure
Standard 5-minute single-trial EPM. Single exposure per animal.
Pre-test setup
- 1.Habituation — Move home cages to the testing room 30 to 60 minutes before the first trial. Lights set to 300 lux measured at the center of the maze.
- 2.Apparatus check — Confirm all four arms are level using a bubble level. Verify illumination is symmetric across arms (within ±10 lux).
- 3.Baseline cleaning — Wipe maze with 70% ethanol; allow 5 min for evaporation before the first subject.
- 4.Camera — Mount overhead camera at least 1.5 m above the maze for full top-down view. Confirm tracking software calibration.
Trial sequence
- 1.Place subject — Center platform, facing closed arm. Same start position for all subjects to avoid bias.
- 2.Record 5:00 — Start tracker on subject release. Standard duration: 300 seconds.1
- 3.Remove subject — Return to home cage. Note any urination or defecation.
- 4.Clean maze — Full 70% ethanol wipe with 90 s evaporation between subjects.
- 5.Counterbalance — Randomize subject order across treatment groups. Test all groups within the same daily window.
Critical methodological constraints
- Single-trial only. Animals cannot be re-tested without losing the anxiety signal (one-trial tolerance, File & Zangrossi 1993). For repeat-measure designs use the modified-EPM (mEPM) variant.4
- Time-of-day matters. Test all subjects within the same circadian window, preferably early dark phase for nocturnal rodents.
- Handling consistency. Stress from handling alone shifts baseline open-arm time. Standardize handler, picking-up method, and transport route from vivarium.
- Sample size. N=8-12 per group is standard for benzodiazepine-class effects (α=0.05, power=0.80, ~40% group difference). Subtler manipulations need N=15-20.
2.2 Measurement & Analysis
The 12 metrics ConductVision auto-scores from EPM video.
Time in Open Arms
Primary anxiety axis
Cumulative duration in unprotected open arms. Higher values indicate reduced anxiety. Sensitive to benzodiazepine challenge: a 1-2 mg/kg dose roughly doubles open-arm time in C57BL/6.1
Open Arm Entries
Approach frequency
Count of full entries (all four paws) into open arms. Read alongside total entries to dissociate anxiety from locomotor effects.
Open Arm Duration Ratio
Primary anxiety index
Open-arm time ÷ total time in either arm type. Normalizes for total exploration. The standard endpoint reported in publications.
Risk Assessment
Ethological measure
Stretch-attend postures plus protected head dips from closed-arm thresholds. Sensitive to low-dose anxiolytics that have not yet shifted open-arm time.3
Closed Arm Entries
Locomotion control
Independent control for general locomotor activity. Use to determine whether reduced total entries reflects sedation versus genuine anxiety change.
+ 7 additional metrics: latency to first open entry, rearing, grooming, velocity by zone, total distance, time in center, head dips.
2.3 Open-arm duration ratio (analysis)
The standard published anxiety endpoint. Computed per animal from the 5-min trial.

§ 4
Discussion
Limitations of the paradigm, methodological caveats, and current directions.
4.1 Common confounds
Variables that shift Elevated Plus Maze results independent of anxiety state.
Asymmetric lighting
If one open arm is brighter than the other, animals avoid it. Always confirm illumination at four arm endpoints is within ±10 lux. The single most common methodological error in EPM data.
Prior testing (one-trial tolerance)
Re-testing on the EPM increases open-arm avoidance even without intervening manipulation. The retest no longer indexes anxiety state. For repeat-measure designs, use the modified-EPM (mEPM) variant which preserves anxiolytic responsivity on retest (Bertoglio & Carobrez 2002).4
Time-of-day
Nocturnal rodents test reliably during their active dark phase. Light-phase testing produces lower baseline activity and compressed group differences.
Handling stress
Animals handled more before testing show higher anxiety-like behavior. Standardize handling: same person, same picking-up method, same transport route from vivarium.
Strain baseline
BALB/c spend ~10% time in open arms; C57BL/6 ~25%. Always report strain, age, sex, and supplier, and run within-strain comparisons before cross-strain claims.3
4.2 Construct validity caveats
Open-arm avoidance is not purely "anxiety". It conflates novelty avoidance, height aversion, and risk assessment. 1 Reproducibility across labs is variable due to lighting, handling, and prior testing history. 2 Recent work emphasizes scoring ethologically-defined behaviors (head dips, stretch-attend postures) alongside the traditional time and entry measures to improve construct validity. 3 When a treatment effect is subtle, ethological measures often outperform zone-time at detecting low-dose anxiolytic activity.
4.3 Special considerations
Is a zebrafish plus maze the same assay as rodent EPM?
No. Zebrafish plus-maze assays use a different apparatus, aversive stimulus, and interpretation frame. Treat them as species-specific anxiety assays rather than variants of the rodent elevated plus maze.
Should I score head dips and stretch-attend postures?
Yes if your treatment effect is subtle. Ethological measures (head dips, stretch-attend, risk assessment) are often more sensitive than zone-time to low-dose anxiolytics. 1 ConductVision automates these from video.
Why has the field shifted toward sex-as-biological-variable reporting?
EPM open-arm time shows reliable sex differences in many strains. NIH SABV mandate plus growing evidence of sex × treatment interactions on EPM measures has driven the proportion of papers reporting both sexes from ~15% (2020) to ~40% (2026).
