Fig. 6.

Spatial relationship between eye-specific inputs in the MGN of adult rewired ferrets. A, B(right), Composite reconstructions of the retinal label from each eye, obtained by superimposing camera lucida drawings of two adjacent MGN sections (see Materials and Methods). Projections from the contralateral eye, stained with WGA-HRP, are represented inred, whereas CTB-stained ipsilateral projections are represented in blue. Only terminal zones are plotted (fibers are not shown). Note that retinal inputs from the two eyes terminate mainly in the same regions of MGN in a nonoverlapping manner (see Results). Right scale bar, 200 μm (valid for bothA and B). A,B, Left, Camera lucida drawings of coronal thalamic hemisections, showing the location (insets) of the retinal label drawn at higher magnification on the right. Left scale bar, 500 μm (valid for both A and B). Abbreviations as in previous figures. Dorsal is up; medial is to the right.
