The spinal ganglia of Torpedo marmorata have been studied in semithin and ultrathin sections with the view to study the formation and possible mode of removal of lipofuscin. This study suggests that osmiophilic bodies among them lipofuscin originate from degenerating mitochondria. These osmiophilic products concentrate at the neuronal cell border with the(More)
The electric discharge of Torpedo M. can be considered as an index of the metabolic activity of the electric lobe of C.N.S. in groups of 10 torpedo the electric discharge was measured: the mechanical stimulus was obtained by the falling of different weights from a determinate height. Other 10 animals, to which the substance was administered, showed an(More)
The electric discharge of Torpedo M. can be considered as an index of the metabolic activity of the electric lobe of C.N.S. In groups of 10 Torpedoes the electric charge was measured: the mechanical stimulus was obtained by the falling of different weights from a determinate height. The experiment was then repeated in conditions of hypoxia: a fall of the(More)
Neuronal lipofuscin has been found in adult Rana e., and in tadpoles at the larval stage with external gills, larvae with internal gills and front legs, and larvae with front and back legs. The lipofuscin granules were positive at many histochemical tests and they had an autofluorescence at 450-470 nm The AA. plan to better define the ultrastructural(More)
