Information processing in the neuron requires spatial summation of synaptic inputs at the dendrite 不同空間和時(shí)間的突觸活動(dòng)在樹(shù)突上的整合過(guò)程是神經(jīng)元信號(hào)處理的重要環(huán)節(jié)。
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 在海馬ca1神經(jīng)元上,短暫的突觸前后神經(jīng)元的反復(fù)相關(guān)活動(dòng)除誘導(dǎo)長(zhǎng)時(shí)程的突觸增強(qiáng)或抑制以外,還能持久地提高或降低樹(shù)突空間整合的線性度。
