Number of dorsal root ganglion neurons and axons in cats of different ages.
Neurons and axons were counted in normal L7 dorsal root ganglia (DRG) and dorsal roots of cats from 2 months to 11 years of age. Over this time period no change in neuronal but a slight increase in axonal numbers were observed. These findings indicate that in contrast to previous reports on male rat lumbar ganglia, neurogenesis in cat DRG does not continue into adulthood.
