Fig. 4.

Camera lucida reconstructions of six retino-MGN axonal arbors in adult rewired ferrets. These axons have focal terminal arbors with large clustered boutons (see Results). Theinsets on the left show a coronal view of the location of each reconstructed axon within MGN. A, Axons 2 and 3 are shown ingray and black, respectively, to demonstrate the overlap between their terminal arbors.B, Partial reconstruction of one cluster (arrowhead) shown in Figure 3A. This cluster was formed by the terminal arbors of several axons (see Fig.3A). Here we reconstructed only three of them.OT, D, and M are as in Figure 3. Scale bar, 100 μm.
