问题 材料题

阅读下面这段话,为大脑中的“杏仁核”下定义。(不超过55字)

        为什么动物和人类会受到惊吓?这得从大脑中的“杏仁核”说起。“杏仁核”位于前脑,即眼睛的正后方。它把感觉和记忆结合起来,是产生“恐惧”等重要性情的物理性源头。

         在一次实验中,美国神经学专家约瑟夫?勒杜克斯先给大鼠放出一个声响,之后再给一次微弱点击。反复多次后,当只给声响时,大鼠同样会产生恐惧。他向大鼠脑中注射了可以映射脑部各个连接部分的染料,并发现听觉丘脑(即脑子通过耳朵接收信号的部分)直接与“杏仁核”相连。随后他把大鼠脑中连接听觉丘脑与“杏仁核”的路径切断,再重复播放声音,发现大鼠不再害怕了。

        “杏仁核”以某种方式形成并储存“恐惧记忆”,一旦“恐惧记忆”识别出这一可怕的信息,它将优先于其他脑部活动。

        研究表明,当恐惧来袭,你脑子的“思考”本能地服从于“杏仁核”。你的恐惧先于你的思考,并启动你的行为。它表示,消除人类的深层恐惧是有可能的,所要做的就是将产生恐惧的相关记忆消除。

“杏仁核”是_____________________________________________

答案

位于人和动物前脑,即眼睛正后方的,能把感觉和记忆结合起来,形成并储存“恐惧记忆”,从而产生恐惧的大脑组织。(意对即可)
