[Morphological changes in the neurons of the rat nucleus raphe dorsalis following application of 5,7-dihydroxytryptamine. A golgi-rapid-impregnation study].

The effect of stereotactically applicated 5,7-dihydroxytryptamine on the demonstrability of the different neuron types of the nucleus raphe dorsalis of the rat was investigated by means of the Golgi-rapid-impregnation technique. Degenerative changes could be demonstrated on the polygonal neurons, only. Typical variations of the dendritic structure was shown on the fusiform neurons. The pyriform neuron typ was not affected.
