Learned Helplessness System
An Essential Tool for Depression Research
The Learned Helplessness Paradigm is a widely recognized animal model of depression, originally described by Overmier and Seligman (1967). This paradigm demonstrates how exposure to inescapable shocks can result in deficits in emotional expression, associative learning, and behavioral coping.
Key Results Metrics
Analyzing Behavioral Coping and Learned Helplessness
Test Duration
Tracks the duration of the test session, indicating overall exposure time and behavioral performance.
Escape Latency
Measures the time taken by the subject to escape the aversive stimulus, reflecting learning and coping mechanisms.
Number of Failures
Counts the failures to escape the shock, serving as a key indicator of helplessness and depressive-like behavior.
Comprehensive Behavioral Analysis
Dynamic Stress-Induced Testing
Automated Behavioral Analysis
Records key behavioral metrics, such as escape latency and avoidance patterns, providing deep insights into stress responses and coping mechanisms.
Comprehensive Experiment Reporting
