OD(%Background) from each layer of the LGN hybridized for GAP-43 mRNA (A, C) and SCG10 mRNA (B, D). A,B, The LGN ipsilateral to the TTX-injected eye.C, D, The LGN contralateral to the TTX-injected eye. The hybridization signals for both GAP-43 and SCG10 mRNAs were reduced in the deprived layers (layers II, III, and V of the ipsilateral LGN and layers I, IV, and VI of the contralateral LGN) of all monocularly deprived monkeys regardless of the length of the deprivation period: 5 d (diamond andsquare), 10 d (triangle andcircle), or 30 d (plus sign).OD(%Background) was measured from a 300-μm-wide column sampling each layer of the LGN. Bars indicate the average of five monkeys.
