Communication between neurons in the brain occurs primarily through synapses made onto elaborate treelike structures called dendrites. New electrical and optical recording techniques have led to tremendous advances in our understanding of how dendrites contribute to neuronal computation in the mammalian brain. The varied morphology and electrical and chemical properties of dendrites enable a spectrum of local and long-range signaling, defining the input-output relationship of neurons and the rules for induction of synaptic plasticity. In this way, diversity in dendritic signaling allows individual neurons to carry out specialized functions within their respective networks.
大脑中神经元之间的通讯主要通过突触进行,这些突触形成于被称为树突的精细树状结构上。新的电学和光学记录技术极大地推动了我们对树突如何在哺乳动物大脑中促进神经元计算的理解。树突多样的形态以及电学和化学特性使得一系列局部和远程信号传导成为可能,从而确定了神经元的输入-输出关系以及突触可塑性的诱导规则。通过这种方式,树突信号传导的多样性使单个神经元能够在各自的网络中执行特定功能。
