Figure 7.

Comparison of MT response properties between SU and MU activity. A, The peak response of MU activity is plotted against the peak SU response, for the MP condition. Data points lie well above the unity-slope diagonal indicating substantially larger MU than SU responses. Data are shown for all recording sites for which MU activity was available (N = 119). B, Comparison of SU and MU peak responses for the BD condition (N = 117). Format as in A. C, DSDI values are compared between MU and SU responses for the MP condition. Same dataset as in A (N = 119). D, Comparison of MU and SU DSDI values for the BD condition (N = 117). E, The preferred depth for MU activity is plotted against the corresponding preferred depth for SU activity. Preferred depths were obtained as the peak of the best-fitting Gabor function (see text). Data are shown for the subset of recording sites for which depth tuning was significant for both MU and SU activity (ANOVA, p < 0.05, N = 47). F, Comparison of MU and SU depth preferences for the BD condition (N = 74).
