Isolation and chemical analysis of neuron soma samples from the cat cochlear nucleus.
Pieces of neuron somata were dissected from the cochlear nuclei of two cats and analyzed for activity of malic dehydrogenase, an important enzyme of oxidative metabolism. Based on location, size and shape the somata were identified as those of spherical bushy cells, octopus cells, and fusiform cells. Somata of cerebellar Purkinje cells were analyzed for comparison. The results suggest that the large cochlear nucleus neurons have malic dehydrogenase activities higher than those of most other neurons so far studied. Also, the octopus and fusiform somata had higher malic dehydrogenase activities than those of the spherical bushy cells.
