... of axon collaterals in regeneration using retro–gradely transported fluorescent dyes. We labelled the axons in the medial brachium with Fast Blue and those in the lateral brachium with Diamidino Yellow in a way that avoided cross–contamination. In normal fish, yellow–labelled ganglion cells dominated...

... the average proportion of labelled cells in dorsal retina had fallen to 25·4 % though the average number in the whole retina was unchanged. Thus a brachial refinement had occurred in parallel with refinement of the retinotectal map. These results support the idea of a selective loss of axon collaterals from...
