Figure 2.
Effect of the BLA or vHipp input to the mPFC on subsequent stimulation of these regions. (a) Subthreshold BLA stimulation was paired with threshold vHipp stimulation at different ISIs (BLA before vHipp as shown in Figure 1). Subthreshold BLA stimulation increased vHipp-evoked spike probability at long ISIs, whereas at short ISIs there was an attenuation of response (**p<0.001, *p<0.05 compared with vHipp-evoked SP at baseline; one-way ANOVA; Dunnett's post hoc test). (b) Subthreshold vHipp stimulation was paired with threshold BLA stimulation at different ISIs (vHipp before BLA). Subthreshold vHipp stimulation failed to significantly affect BLA-evoked spike probability across the ISIs tested.
