研究方向

人腦創造了許多高科技的產物,甚至建造了超級電腦,可是我們對自己腦是如何運作的卻依舊非常地模糊。揭開大腦是如何運作是一個令人著迷的問題,本實驗室目前的研究主題主要是專注在情緒焦慮,抗憂鬱藥物,認知學習記憶,生理運動,與腦神經老化方面。研究的方法主要是以小鼠的動物模式,來探討基因,腦神經細胞結構,生理賀爾蒙與動物行為,希望藉此來試著解開基因與神經的運作之謎。

目前實驗室的研究有以下幾個議題:

1) 個體成年後, 腦中增生的新神經細胞, 其生理上的功能為何?

2) 運動如何讓我們的腦神經細胞更健康,是透過如何機制?

3) 要如何讓年老的腦神經細胞年輕化?有哪些可能的候選因子?

4) 哪些基因在抗憂鬱或影響學習行為中扮演角色? 其背後的機轉為何?

Understanding how the brain works is among the most important challenges to 21st century science. One structure in the brain that has received considerable attention is the hippocampus, which is considered to play a part in learning and emotional regulation. Intriguingly, even in adults, new neurons continue to be born within the hippocampus. Scientists have assumed that the function of these newly born neurons in the adult hippocampus are linked to learning and emotion.  Unfortunately, there is still no consensus on what functions these new neurons perform.  It is important to unveil factors controlling the activity of the progenitors of these new neurons, the neuronal stem cells, and to investigate the functions of newly-formed neurons.  Our current work is focus on three projects:
1)  What are the functions of adult born hippocampal neurons?
2)  How does exercise benefit our brain, and by what molecular mechanism?
3)  How to make the aging brain younger?  What are the candidate factors?
