Figure 6

Scatter plots for the regression analysis. The response amplitudes at 0.33s and 1s ISIs are normalized to the response amplitude at the 2s ISI for each measurement method. Each plot shows the averaged amplitudes in one measurement method against another. The averaged amplitudes in one measurement metric recorded from three hemispheres are combined to make the scatter plots. The amplitudes at the 2s ISI are removed from the plots, since data were normalized to these values. A trend-line is fitted based on the six paired data points from the three hemispheres in each plot. The slope of the trendline and R² for the fit is shown in each plot.
