Lowering extracellular ca2 + or intracellular ca2 + in the postsynaptic neuron actually attenuated the development of activity - dependent response enhancement . furthermore , intracellular injection of spermine or administration of ryanodine eliminated the activity - dependent response enhancement . taking together , our data demonstrated that short - term enhancement of signal transmission to lhc might occur via calcium - dependent mechanism located at 本文第三部分工作,分別比較了r / ghc對(duì)紅光反應(yīng)和對(duì)綠光反應(yīng)、 lhc對(duì)紅光反應(yīng)和r / ghc對(duì)紅光反應(yīng)來(lái)驗(yàn)證級(jí)聯(lián)模型的正確性,結(jié)果顯示r / ghc可能還接受來(lái)自紅敏視錐的直接輸入。
