Case MV2n2. Reconstruction of a V2 thin stripe injection and labeled neurons in a 2-week-old macaque. A: Reconstruction of labeled cells throughout the brain of a 2-week-old macaque after a CTB injection into a thin stripe in V2. The star and gray halo represent the injection site location and spread, respectively. Solid black lines represent borders between visual areas determined with cytochrome oxidase; dashed black line presents the estimated horizontal meridian. B: A lateral view of the macaque brain before artificial flattening. The highlighted area corresponds to the area of the brain shown in A. C: A magnified view of CTB label along the V1/V2 border overlaid with CO stripe and blob borders determined by using images D and F. D: Cytochrome oxidase photomicrograph showing the stripe type pattern in V2. E: A photomicrograph of a portion of V1 (boxed area from C) of a single CTB section with retrogradely labeled cells. F: Cytochrome oxidase photomicrograph demonstrating the blob pattern in V1. Tn, thin stripes; Tk, thick stripes. For other abbreviations, see list. Scale bar = 2 mm in A,C,D,F; 0.25 mm in E.
