神经细胞如何连接?6张图为您揭秘!

1.神经元是构成神经系统结构和功能的基本单位。细胞突起是由细胞体延伸出来的细长部分,细胞突起又可分为树突和轴突。每个神经元可以有一或多个树突,可以接受刺激并将兴奋传入细胞体。每个神经元只有一个轴突,可以把兴奋从胞体传送到另一个神经元或其他组织。 2.人的大脑就是由神经细胞所组成的错综复杂的网络系统,这些神经细胞相互之间通过突触间进行交流。任何声音、景物、身体活动,只要是新

1.神经元是构成神经系统结构和功能的基本单位。细胞突起是由细胞体延伸出来的细长部分,细胞突起又可分为树突和轴突。每个神经元可以有一或多个树突,可以接受刺激并将兴奋传入细胞体。每个神经元只有一个轴突,可以把兴奋从胞体传送到另一个神经元或其他组织。

2.人的大脑就是由神经细胞所组成的错综复杂的网络系统,这些神经细胞相互之间通过突触间进行交流。任何声音、景物、身体活动,只要是新的,都会使得脑中某些神经元的树突和轴突生长,与其他神经元连接,构成新的网络。

3.维多利亚大学医学科学系研究人员就通过观察细胞培养中的神经元的生长揭示了其中的奥妙。

培养中的神经干细胞

这些是研究人员在一个培养基中,用相差显微镜记录下4个小时内神经干细胞生长动态照片。它们揭示了神经元间通过树突和突触建立相互关联的动态生长的过程。这些细胞的社会行为,创造了大脑令人难以置信的意识属性。

4.通过突触之间的连接,使不同的信息在神经系统中实现了连接,这是人类智能记忆的原理。你的大脑也正在做同样的事。当你记忆某件事或学习某事物时,神经元就会重新布线连接,不断地发生改变。这实在是太酷了!

 连接创造价值!
