NE modifies differentially PPR. (A) camera lucida drawing of a biocytin-injected neuron displaying the typical basal and apical dendritic arborization of a neocortical pyramidal cell. (B, C) Effects of NE on eIPSCs PPR. (B) NE facilitated PPR in LI-eIPSCs (n = 19), while (C) depressed it in LII/III-eIPSCs. (D) Variation of the pair pulse ratio PPR(NE)/PPR(control) for LI- and LII/III-eIPSCs; the NE-induced change in PPRs do not overlap, suggesting that 2 types of presynaptic GABAergic terminals are differentially modulated by NE.
