Effects of DR on RF size in wild-type and BDNF transgenic mice. (A) Examples of peristimulus time histograms for cells recorded in primary visual cortex of LRWT, DRWT, and BDNF transgenic mice. Vertical stimulus bar, contrast 90%; velocity 28°/sec. Calculated RF sizes are: LRWT, 16.5°; DRWT, 32.5°; LRBDNF, 18.3°; DRBDNF, 14.75°. (B) RF size distribution for each group of mice. RFs were divided into 10 classes of 5° each, from 0° to 50°, and plotted as percentage of cells. Median RF size in DRWT (20.29°, 116 cells, eight mice) is significantly larger than that obtained in LRWT (16.80°, 77 cells, five mice; Kruskal–Wallis ANOVA, P < 0.05; post hoc Dunn's test, P < 0.05). On the other hand, median RF size in DRBDNF (18.50°, 65 cells, seven mice) is identical to that obtained in LRBDNF mice (18.44°, 69 cells, five mice).
