So one way that neurons, in particular, are able to communicate with other cells in the nervous system, share information, integrate information, decide what to do next is that they are physically connected to other different cells.

所以神经细胞之所以能够,与神经系统中其他细胞通讯,分享信息,整合信息,从而决定下一步该做什么,是由于不同细胞间,是彼此连接在一起的

These junctions, these red dots here are actually made up of proteins, some are synthesized by one cell, some are synthesized by each other, and they lock together to form a very tight barrier, to form a tight junction between the two cells.

这些红点表示细胞连接,实际上是由蛋白质构成的,有些是由一个细胞单独生成的,有些是由两个细胞共同生成,使这两个细胞紧锁在一起形成紧密的屏障,并在两细胞间形成紧密连接
