压力往往会对认知产生有害影响。我们发现,在基于鼠标触摸屏的选择任务中,适度的压力增强了后期反转学习。腹内侧额前皮质(VmPFC)损害模拟应激的影响,而眼眶前额叶(OFC)和背外侧纹状体(DLS)损害损害逆转。脑源性神经营养因子注入vmPFC可阻止应激易化效应的逆转。这些发现提示了一种机制,即应激诱导的vmPFC功能障碍通过交替(如纹状体)系统抑制学习。
Stress often has deleterious effects on cognition. We show that moderate stress enhanced late reversal learning in a mouse touchscreen-based choice task. Ventromedial prefrontal cortex (vmPFC) lesions mimicked the effects of stress, while orbitofrontal (OFC) and dorsolateral striatal (DLS) lesions impaired reversal. Stress-facilitation of reversal was prevented by BDNF infusion into the vmPFC. These findings suggest a mechanism in which stress-induced vmPFC dysfunction disinhibits learning by alternate (e.g., striatal) systems.
