Table 1.
Tabulation of the number of tests of rats that in response to stimulation by intense focused ultrasound (iFU) withdrew their ipsilateral (Ipsi) paw versus contralateral (Contra) paw versus both paws in a consistent fashion as a function of surgery type or as right vs left for the control (no surgery) animals. Here pSNL refers to those rats whose sciatic nerve received a partial ligation while ‘sham’ refers to those animals whose sciatic nerve was surgically exposed, but not ligated. ‘NT’ refers to those animals for which we could not find a threshold value of iFU stimulation.
pSNL | Sham | Control | |||
---|---|---|---|---|---|
Ipsi | 58 | Ipsi | 21 | Right | 1 |
Contra | 0 | Contra | 20 | Left | 3 |
Both | 1 | Both | 7 | Both | 1 |
NT’s | 0 | NT’s | 10 | NT | 7 |
Total: | 59 | Total: | 58 | Total: | 12 |
# tests used for t-test | 58 | # tests used for t-test | 58* | # tests used for t-test | 12* |
Note that during some tests our device reached the maximum intensity it could emit yet did not allow us to obtain an iFU threshold value. For this circumstance we therefore used this maximum value in the t-tests as a proxy for the (assumed higher) true threshold.
