    • Now, when people hear the term networks, they think, oh, hardwired together, and that is sometimes true in the brain, and there are hardwired connections in the brain, and they're myelinated, which is basically a way of insulating kind of the neuronal connections for faster information transmission, but as a general rule, we'll have what are known as functional networks, where a bunch of different neurons are organized into what's called a cell assembly, and basically, they're all active at the same time.

      現在,當人們聽到 "網絡 "這個詞時,他們會想到 "哦,硬連接在一起",這在大腦中有時確實存在,大腦中也有硬連接,而且是有髓鞘的,這基本上是一種絕緣神經元連接的方式,以加快資訊傳輸速度,但一般來說,我們會有所謂的功能網絡,在這種網絡中,一群不同的神經元被組織成所謂的細胞集合體,基本上,它們在同一時間都處於活躍狀態。
