TABLE 2.Effect of K⁺ channel blockers on spontaneous activity



	Axotomy + ACSF	Axotomy + TEA	Axotomy + 4-AP

Number of animals	3	3	3
Incidence of Spontaneous activity, %	21.1 ± 0.5	31.5 ± 1.0	31.8 ± 2.9
P value vs. ACSF	—	0.0001	0.0001
Total number of fibers recorded	503	555	576

Incidence of spontaneous activity determined on post-operative day (POD) 7 after perfusion of the injured nerve with K⁺ blockers TEA (10 mM) or 4-aminopyridine (4-AP; 10 mM), or with vehicle (ACSF). The pump was still in place at the time spontaneous activity was measured. SEs are based on comparison between different animals. P values are based on Fisher's exact tests on the combined data. There was no significant difference between the TEA and 4-AP groups.
