In
Figure 6, recorded “true” SS and synthetic SS (synSS) averaged population responses are shown. Responses are presented in their original unfiltered forms (left column) and after filtering using the first five harmonics (right column) for all five rates. For each rate, the PERG
SS is displayed as the middle trace (red, unbroken trace). Synthetic responses using deconvolved qPERG
tr (synPERG
SS) are displayed above the true PERG
SS (black, dashed trace) while synthetic responses using conventional 2.2 rps transients (synPERG
SS(2rps)) are displayed below the true PERG
SS (blue, dotted trace). The synthetic response computed using the tr response at 2.2 rps, differs from the other two substantially at high reversal rates (15.4, 17.4, and 26.5 rps). Correlation coefficients between true PERG
SS and both versions of synPERG
SS are displayed in
Table 2. While both synthetic responses exhibit high correlation to true PERG
SS responses at low rates (correlation of 0.99), as reversal rate is increased, the synthetic constructed with extracted qPERG
tr accounting for adaptation effects (synPERG
SS) maintains a high correlation with the true PERG
SS (>0.96 for all rates), while the synthetic response constructed from conventional 2.2 rps transiet PERG (synPERG
SS[2rps]), becomes progressively less able to predict the true PERG
SS (correlation of 0.65 at 26.5 rps).
