Probabilistic Reversal Learning (PRL) for Rats

Details

Designed to measure sensitivity to valence (i.e. positive and negative) feedback information, PRL is sensitive to serotonergic manipulations, suggesting this test may be used to study depression-relevant behaviour in rodents

Example Neural Systems Involved

• Serotonin

Clinical Areas Showing Impairment

• Depression

Cognitive Functions Covered

• Emotional cognition and responding to reinforcement

Typical Training Times (depends on strain and age)

• 1-2 weeks to train to touch the screen and initiate the task
• ~17 sessions training to the task
