Task: Question Generation
Input (English): Context: Clinical trials have shown promising results with the use of subcallosal cingulate gyrus deep brain stimulation (DBS) for treatment-resistant depression. However, strategies to manage patients who do not respond to this therapy have not been explored in detail. In rats, DBS in the ventromedial prefrontal cortex (vmPFC) induces a significant antidepressant-like response in the forced swim test (FST). We have used this test to investigate potential interactions between DBS and clinically used augmentative regimens.', 'Rats undergoing the FST were treated with vmPFC DBS along with different augmentative drugs, namely buspirone, risperidone and pindolol. Locomotor activity was tested in an open field.', 'DBS induced a significant reduction in immobility scores as compared to saline treated controls. These antidepressant-like effects, however, were not potentiated by the co-administration of buspirone, risperidone or pindolol.
Answer: Despite having good predictive validity, animal models are limited from a translational perspective.
Output (English): Do augmentative therapies potentiate the antidepressant-like effects of deep brain stimulation in rats?
