Description of Surgical Groups1,2

Surgical Group Status of Chorda Tympani Nerve (CT) Status of Glossopharyngeal Nerve (GL) Final Group Size3
SHAM Intact Intact N=4
CTx Transected Intact N=5
GLx Intact Transected N=4
CTr + GLr4 Regenerated to anterior tongue Regenerated to posterior tongue N=3
CTr + GLx4 Regenerated to anterior tongue Transected N=4
CTx + GLr (unil) + GLx Transected Bilaterally transected, unilaterally regenerated to the posterior tongue N=4
CT-PostTongue Regenerated to posterior tongue Transected N=4
GL-AntTongue Transected Regenerated to anterior tongue N=5
1

All transections are bilateral unless otherwise noted.

2

Six rats received a CTx + CTr (unil) + GLx surgery, but only two animals were histologically confirmed so those animals were not included in the paper.

3

Some animals were discarded due to problems that occurred during testing or because histological analysis indicated inappropriate regeneration or lack of regeneration.

4

The CTr+GLr group was combined with the CTr+GLx group for statistical analysis to increase power because there was no obvious difference in the postsurgical behavior of these rats.
