Within-train plasticity of fast PSPs. (A) Likelihood of increase (+), decrease (−), or lack of change (0) in the amplitude of the fast PSP from the first to the fifth fast PSP within a stimulus train measured in all five followers. Data are shown separately for EPSPs and IPSPs. Note that for B3, there are few EPSPs, and for B8a/b and B61/B62 there are few IPSPs. (B) Percent net change in amplitude from the first to the fifth PSP within a stimulus train measured in all five followers. Data are shown separately for EPSPs and IPSPs. Boxes show upper and lower quartiles. The line within the box is the median, and × is the mean. Dashed line at zero. Outliers are not shown but were included in all calculations.
