We aim to understand cross-species mechanisms by which genetic programs and postnatal environment regulate brain development and dysfunction at different levels. To do this, we use state-of-art molecular, cellular, circuit, physiological, anatomical and behavioral approaches in mouse and non-human primates. Our recent work demonstrated that visual experience is required for both the functional and cell-type specification of L2/3 glutamatergic neurons in the mouse primary visual cortex (Tan et al., Neuron 2020, Current Biology 2021, J. Neurosci. 2022; Cheng, Butrus and Tan et al., Cell 2022). We are building up and expanding our research topics from these findings, to ask how postnatal environment regulates the development of cell-type specific circuits at whole brain level. In addition, we are trying to rebuild functional circuits in animal models of nervous system injury. The ultimate goal of our research is to treat brain dysfunction in human.

我们实验室研究遗传程序和出生后的环境在不同水平上调控大脑发育和功能障碍的跨物种机制。 为此,我们在小鼠和非人类灵长类动物中使用最先进的分子、细胞、环路、生理学、解剖学和行为学方法。 我们最近的工作表明,小鼠初级视觉皮层中 L2/3 谷氨酸能神经元的功能和细胞亚型确立都需要视觉经验(Tan et al., Neuron 2020, Current Biology 2021, J. Neurosci. 2022; Cheng, Butrus and Tan et al., Cell 2022) 。 我们正在根据这些发现建立和扩展我们的研究课题,以探究后天环境如何在全脑水平上调节由特定细胞亚型构成的环路的发育。此外,我们正尝试在神经系统损伤的动物模型中重建功能环路。 我们研究的最终目标是治疗人类的脑功能障碍。
