Figure 2: Normal gain between ERG components. The gain relationship between two ERG components is established by linear regression (thick line) of normalised upstream to the downstream ERG parameter for a group of control animals (unfilled circles) measured on 5 separate occasions. A slope of unity is represented by the thin diagonal lines. Statistics for this analysis are represented in Table 1. Correlations of (a) PIIIamp and PIIamp give slopes which are near unity. Correlations that produce slopes steeper than unity include (b) PIIamp and pSTRamp (c) and and (d) and PIIit. Slopes shallower than unity were observed for correlations between (e) and pSTRit and (f) PIIit and nSTRit.
