Abstract
Compared to dorsal root ganglion (DRG) neurons at L(5) in rats, DRG ne urons at L(7) in cat have a larger mean soma size, a bimodal rather th an unimodal distribution of sizes and lower succinate dehydrogenase (S DH) activities for neurons of all sizes. In contrast to spinal motoneu rons in both cats and rats, the larger DRG neurons have the higher SDH activities. The 10-20% higher SDH activity of DRG cells in rats than in cats may reflect, in part, a species difference of about 40% in met abolic rates.
