Figure 2. Orientation organization of V1 inputs to V2 orientation columns in 4 representative cases.

Figure 2.

(A) CTB647 (purple oval) and CTB488 (green oval) injection sites in V2, and resulting labeled cells in V1 (purple and green dots, respectively) are shown superimposed onto the imaged 0° retinotopic map for case MK373. The orientation map for the region inside the dashed white box is shown in panels (B-C). Other conventions are as in Fig. 1. (B) TOP: The locations of the CTB647 injection site in V2 (black oval) and resulting labeled cells (black dots) in V1 are shown superimposed to the composite orientation map for the same case shown in (A). BOTTOM: Distribution of POs at the V2 CTB647 injection site (gray bars; right Y axis) and under the CTB647 labeled cells in V1 (colored bars: left Y axis). (C) Same as (B), but for injection case MK373-CTB488. (D-F) Same as (A-C), but for two additional injection cases: MK368-CTB555 (D-E), and MK368-CTB488 (D,F). Scale bars: 1mm. The reminder of cases used in this study are shown in Extended Data. Fig. 2.
