还有类似菲尼亚斯,盖奇的其他例子,这个人受到伤害的大脑部位,与他相同,部分大脑皮层。
We talked about the auditory cortex the first section and maybe there are other parts of the brain that are factoring in here as well but how is it that composers send this information to let's say, our auditory cortex here?
我们在第一节课的时候谈到过听觉皮层,也许大脑的其他部分,也参与了进来,但作曲家是怎么做到把这些信息,传送到我们所谓的听觉皮层的呢
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
The other thing we know about the brain is that the cortex is absolutely essential for is interpreting the features such as that facial expression, color.
我们还知道,大脑皮层对于解释面部表情,颜色等特征发挥绝对根本的作用。

你的脑袋里存在着这些定位图,但你们会发现,这些定位图是你大脑皮层的一部分,但你们会发现,这是在你的大脑活动中,起到重要作用的一部分大脑皮层,不过只有不到四分之一的大脑皮层,存在这些定位图或是投射区
00 times electrode is only 1 mm long that penetrates just the most outer layers of the outer regions of your brain called into the distributable cortex.
