Normal Numbers of Retinotectal Synapses During the Activity-Sensitive Period of Optic Regeneration in Gsldfish : HRP-EM Evidence Implicating Synapse Rearrangement and Collateral Elimination During Map Refinement


Optic and nonoptic fibers and synapses were counted in the primary optic innervation layer (S-SO-SFGS) in anteromedial tectum in normal goldfish and in fish 30, 60, and 240 d after the optic nerve was crushed. A newly developed “cold-fill” HRP-labeling protocol was used to label optic afferents for electron microscopy, and counts were then made on EM… (More)
