So this cell, wherever it's setting, wherever it is positioned within the nervous system let's say in the cortex somewhere or the outside surface of the brain is able to communicate with a region of the brain that's in this direction, a region in this direction, a region in this direction, a region in this direction.
所以这个细胞 无论它在何处,无论它在神经系统中安身何处,就比方说它位于大脑皮层上吧,即位于大脑外表面上的某处,它可以同,这一方向上的脑域进行交流,也可以是这个方向,也可以是这个方向,也可以是这个方向

There are other cases like Phineas Gage, cases where people have had damage to that same part of the brain, parts of the frontal cortex.

-
This is generally the general introduction of the brain that I wanted to provide, giving the framework for what I'll be talking about later on throughout the course so that I might later on make reference to neurons or neurotransmitters or the cortex or the left hemisphere and you'll sort of have the background to understand what I'm talking about.
以上这些就是我所要讲的,关于大脑的综述,为我以后要讲的课程,建立起框架,往后我可能会提到神经元,神经递质,大脑皮层,或是大脑左半球,而拥有了背景知识的你们,便能够理解我在讲些什么
