Figure 8.
Deficits in DVRs after ibotenic acid lesions: dependence on the estimated extent of the lesions in MSTd, MSTl, and MT (data for each of the five monkeys). Ordinates, Percentage reduction in the DVRs for each monkey, based on the changes in the peak-to-peak amplitudes (Ap-p) of the least-squares best fits obtained with Equation 1 shown in Figure 7 (the parameters are listed in Table 3). Abscissas, Percentage of each designated subregion of the STS showing morphological damage in any layer (gray symbols, complete plus partial lesions) or all layers (black symbols, complete lesions). Lines are best-fit linear regessions (taking into account the variance of both X and Y), the coefficients of which are shown at the bottom right in each panel (coefficients of determination are in parentheses). Data in open symbols (monkey P) were excluded from the regressions.
