Summary Using a modified Alcian blue/Alcian yellow method, differences in stainability in the fibres of the preoptic-hypophyseal tract of Rana temporaria were observed. Near the preoptic nucleus most of the fibres stained yellow, in the tract the fibres stained lightgreen or showed green inclusions on a yellow background, whereas at the fibre-endings a colour switch to blue-green was found. This colour switch was the most pronounced in the neural lobe, where the neurosecretion stained blue-green, whereas in the fibre-endings in the outer zone of the median eminence a colour switch to green was noticed. The results can best be explained with the assumption that a modification or transformation of the neurosecretion occurs during its transport from the preoptic nucleus to the fibre-endings. Literature related to this hypothesis is discussed.
