大脑科学在今后的譬如五十年内,可以达到什么水平?试图回答这一问题的生理学家将会遇到两大困难。首先必须知道其它学科的发展情况。离开了这些学科,大脑生理学的发展是不可思议的。现在生理学家的研究已经成功地进入大脑深处:借助比头发细150倍的电极记录神经细胞的电位;把化学物质注入单个神经元;显示神经细胞之间的相互联系;确定神经细胞个别部分的作用。在学者们看来,亿万大脑细胞象是无数微型的电子工厂和化学工厂,而整个大脑则象自然中结构最完善的一个系统,它的奥秘还有待于彻底揭开。但是如果没有
What level of brain science can be achieved within the next 50 years? Physicists who are trying to answer this question will encounter two major difficulties. It must first know the development of other disciplines. Leaving these disciplines, the development of brain physiology is incredible. Now physiologists’ research has successfully entered the depths of the brain: recording the potential of nerve cells with electrodes 150 times finer than hair; injecting chemicals into individual neurons; showing the interconnections between nerve cells; and determining the individual parts of nerve cells effect. In the eyes of scholars, billions of brain cells are like countless miniature electronic factories and chemical factories, and the entire brain is like a system with the most complete structure in nature. Its mystery remains to be fully unveiled. But if not
