Figure 4.

Greater potentiation occurs in distal inputs when paired with strong activation of a colocalized synaptic input, than when paired with remote synaptic activation or somatic current injections. A, Schematic of the protocols used to induce plasticity. B, Potentiation ratios of dSR inputs. Significant potentiation of the distal input was observed for all conditions (one-way ANOVA with repeated measures, p < 0.01, not indicated), except for the case of unpaired dSR during weak pSR paired with current injection. Comparisons of potentiation across groups were made using one-way ANOVA with post hoc Bonferroni tests compared with the reference case of weak dSR paired with strong pSR (*p < 0.05, **p < 0.01).
