Article Synopsis
- - The study investigates how repeated aversive stimuli lead to long-term sensitization (LTS) in Aplysia, affecting defensive reflexes and suppression of feeding behaviors.
- - Researchers discovered that LTS training decreases the excitability of a key decision-making neuron (B51) in the feeding circuit, which recovers after 72 hours when LTS is no longer present.
- - The study concludes that while B51 plays a crucial role in feeding suppression, serotonin treatment to induce LTS does not impact feeding or B51's excitability, indicating serotonin is not involved in this process.
In Aplysia, noxious stimuli induce sensitization of defensive responses. However, it remains largely unknown whether such stimuli also alter nondefensive behaviors. In this study, we examined the effects of noxious stimuli on feeding.
