Receptive field area and response quality are similar in wild-type and knock-out mice. A, Receptive field area is similar in wild-type and knock-out mice. The histogram is based on 6 WTB6, 11 WTB6 MD, 5 ACB6-/- MD, and 8 RIIβ-/- MD mice (data were not collected for 129 background mice). B, C, The levels of visually driven and spontaneous activity were also similar in wild-type and knock-out mice, as rated on a three-point activity index (1 = low to 3 = high; see Materials and Methods). Histograms are based on 6 WTB6, 6 WT129, 11 WTB6 MD, 6 WT129 MD, 6 ACB6-/- MD, 5 AC129-/- MD, and 11 RIIβ-/- MD mice. Other conventions as in Figure 1.
