The effects of monocular deprivation in the LGN contralateral to the TTX-injected eye. This figure shows the results of the same monkey as in Figure 4. The hybridization signals for both GAP-43 and SCG10 mRNAs were lower in layers innervated by the TTX-injected eye (layers I, IV, and VI) than in layers innervated by a normal eye (layers II, III, and V). A, Nissl-stained section. B, Cytochrome oxidase-stained section.C, OD(%Background) from a 300-μm-wide column sampling all layers of Nissl-stained LGN (A). D,OD(%Background) from cytochrome oxidase-stained LGN (B). E, Localization of GAP-43 mRNA. F, Localization of SCG10 mRNA.G, OD(%Background) from the LGN hybridized for GAP-43 mRNA (E). H,OD(%Background) from the LGN hybridized for SCG10 mRNA (F). Scale bar, 1 mm.
