研究概述

奖赏与惩罚驱使动物接近或逃避、产生快乐与痛苦、并指导学习与记忆形成。奖赏与惩罚关乎动物的生死与种系繁衍、并在人类的日常生活中影响情绪与情感。小鼠与人有类似的神经环路,并对奖赏与惩罚有相似的行为反应。我们实验室以转基因小鼠为模型,研究哺乳动物处理奖赏与惩罚的神经环路机制,特别是中缝背核及内侧缰核两个脑区及相连的神经环路的作用。我们运用电生理和光学成像,从清醒小鼠中记录特定类型神经元的在奖赏与惩罚相关行为中的反应特点。继而运用光遗传学及化学遗传学手段,检测激活、抑制、损毁相关神经元对于行为的影响。我们也利用全细胞膜片钳和光学成像等手段,探索不同药物及细胞信号转导途径在奖赏与惩罚行为中的作用及分子细胞机制。脑内处理奖赏与惩罚的神经环路异常导致多种人类精神疾病,包括抑郁、精神分裂、药物成瘾等。因此,我们的工作不仅有助于理解与奖赏与惩罚相关行为的神经生物学基础,亦可具有临床意义。
