Figure 4.

Distribution patterns of retrograde labeling in FEF and LIP after double injections of FB and DY into MT or V4 (monkey Da). Six representative coronal sections through FEF (A–D) or LIP (E, F) are arranged anteroposteriorly. The approximate anteroposterior levels of the sections are indicated in the lateral view of the brain. The extents of the injection sites of FB (green) and DY (red) are exemplified in a coronal section at lower-right, part of which is enlarged in F. The retinotopic extents of the injection sites are shown in an adjacent diagram of the contralateral hemifield (eccentricities denoted by numbers). Green dots, FB-positive neurons; red dots, DY-positive neurons; blue dots, double-labeled neurons. CA, Calcarine fissure; IO, inferior occipital sulcus; IP, intraparietal sulcus. Other abbreviations are as in Figure 1.
