Autoradiographic demonstration of 3H-labelled glycoproteins in 'light' and 'dark' neurons of different grisea of rat brain after intraventricular application of tritiated fucose

The simultaneous demonstration of 3H radioactivity and of 'light' and 'dark' neurons by histological staining revealed that the occurrence of 'light' and 'dark' neurons are morphological correlates of different activity stages of cell metabolism. In this connection it became evident that 'light' nerve cells incorporated significantly greater amounts of fucose and therefore should be regarded as metabolically more active. (author)
