Information processing in the neuron requires spatial summation of synaptic inputs at the dendrite 不同空间和时间的突触活动在树突上的整合过程是神经元信号处理的重要环节。
In ca1 pyramidal neurons of the hippocampus , a brief period of correlated pre - and postsynaptic activity , which induces long - term potentiation ( ltp ) or long - term depression ( ltd ) , results in a persistent increase or decrease in the linearity of spatial summation , respectively 在海马ca1神经元上,短暂的突触前后神经元的反复相关活动除诱导长时程的突触增强或抑制以外,还能持久地提高或降低树突空间整合的线性度。
