The Repeated Acquisition and Performance Chamber (RAPC) is a specialized behavioral testing apparatus designed to assess both learning acquisition and performance retention in rodents. This chamber features five discrete equidistant compartments connected by three sets of one-way doors, creating a sequential navigation paradigm that allows researchers to evaluate cognitive flexibility, discrimination learning, and reversal learning protocols. The system alternates between learning and performance components across sessions, enabling comprehensive assessment of both initial acquisition and established performance under different auditory stimulation conditions.
Available in both manual and automated configurations for mice and rats, the RAPC provides a standardized environment for investigating motor learning, sequential learning paradigms, and cognitive behavioral phenotyping. The automated version integrates with Conduct software for precise experimental control and real-time data capture, making it particularly valuable for studies requiring consistent protocol execution and detailed behavioral tracking across multiple sessions and trials.
How It Works
The RAPC operates on the principle of sequential learning paradigms where animals navigate through a linear series of compartments using one-way doors to reach a goal location with positive reinforcement. The chamber's design creates a unidirectional pathway that requires subjects to learn and remember specific navigation sequences, with different auditory stimuli providing contextual cues for learning versus performance components.
During experimental sessions, subjects begin in the start box and must traverse through the compartments following the established sequence to reach the saccharin reinforcement at the goal box. The alternating session structure allows researchers to distinguish between initial learning acquisition (where new sequences are established) and performance retention (where previously learned sequences are executed), providing distinct measures of cognitive flexibility and procedural memory.
The automated version employs sensor tracking at each one-way door to capture precise timing and movement data, enabling quantitative analysis of navigation efficiency, error patterns, and learning curves across the three trials per session and multiple sessions per component structure.

Practical Tips
Verify sensor detection accuracy at each one-way door using test objects before beginning experimental sessions.
Why: Ensures reliable data capture and prevents loss of critical behavioral timing information during protocols.
Clean door tracks weekly and inspect one-way door mechanisms for smooth operation to prevent navigation impediments.
Why: Maintains consistent chamber function and prevents mechanical issues that could confound behavioral measurements.
Conduct habituation sessions before experimental protocols to familiarize subjects with chamber environment and reduce novelty effects.
Why: Establishes baseline navigation behavior and improves reliability of learning acquisition measurements.
Monitor initial trial completion times to identify subjects requiring extended habituation before beginning formal protocols.
Why: Ensures subjects are motivated to complete navigation sequences and prevents data exclusion due to incomplete trials.
Maintain consistent auditory stimulation timing and intensity across learning and performance components.
Why: Provides reliable contextual cues that enable subjects to discriminate between different protocol phases.
If subjects show reluctance to traverse doors, verify saccharin reinforcement delivery and check for door obstruction.
Why: Maintains motivation and ensures proper navigation sequence completion for valid behavioral assessment.
Ensure door openings are appropriately sized for target species to prevent injury during navigation.
Why: Protects animal welfare while maintaining proper experimental conditions for behavioral testing.

Compliance
What is the difference between learning and performance components in the RAPC protocol?
Learning components involve acquisition of new navigation sequences with novel contingencies, while performance components assess execution of previously established sequences. Both use different auditory stimulation to provide distinct contextual cues.
How does the sensor tracking system capture behavioral data in the automated version?
Each one-way door is equipped with sensors that detect subject entry and generate switch closure events, capturing door crossing timing and sequence data displayed in real-time through Conduct software integration.
Can the chamber be used for both acquisition and reversal learning protocols?
Yes, the alternating session structure and one-way door design specifically enable both initial acquisition studies and reversal learning paradigms by modifying reinforcement contingencies between components.
What type of reinforcement schedule is recommended for RAPC studies?
The system uses positive reinforcement with saccharin delivery at the goal location, providing consistent motivation without requiring food restriction or aversive stimuli that could confound learning measures.
How many animals can be tested simultaneously in a single chamber?
The RAPC is designed for individual subject testing with one animal per chamber session to ensure accurate behavioral tracking and eliminate social interaction variables.
What maintenance is required for the one-way door mechanisms?
Regular inspection of door movement smoothness and sensor calibration (automated version) is recommended, along with periodic cleaning of door tracks to prevent debris interference with navigation.
Can the chamber dimensions be modified for different research applications?
The chamber provides fixed dimensions optimized for each species, but the five-compartment structure and door spacing represent standardized parameters for consistent cross-study comparisons.
