Learned Helplessness (LH) Model Development Service

Are you currently facing long drug development cycles and challenges in identifying effective therapeutic targets for CNS disorders? Our learned helplessness (LH) model development service helps you accelerate drug discovery by providing a highly predictive and translatable platform for preclinical testing. We achieve this through advanced behavioral phenotyping, meticulous methodological design, and comprehensive neurobiological readouts.

The LH model is a well-established and widely used animal model for studying depression and the efficacy of antidepressant treatments. It is based on the theory that exposure to inescapable and unpredictable stress leads to a state of passivity and a deficit in escape behavior. This behavioral phenotype mimics core symptoms of major depressive disorder in humans, making it a powerful tool for preclinical research. The model's predictive validity has been demonstrated in its sensitivity to a range of clinically effective antidepressants.

Learned Helplessness (LH) Model

The core of our service is the Learned Helplessness (LH) model itself. It is a robust and long-standing paradigm that involves exposing an animal to repeated, unavoidable aversive stimuli. Over time, a subset of the animals develops a "helpless" phenotype, characterized by a failure to escape from a mild aversive stimulus, even when an escape route is available. This passive coping strategy is considered an endophenotype of depression. We are experts in not just implementing this model but in optimizing it for your specific research needs. We use a shuttle box apparatus with a shock floor that is precisely calibrated to deliver the aversive stimulus.
