General Properties of Polymodal Nociceptor Fibers Recorded in Intact and Lesioned Corneas at Different Times After Lesion With Microkeratome

		Injured Corneas (Time After Lesion)
Polymodal Nociceptors	Intact Corneas	3–8 h	24–48 h	72 h	6–15 Days
Spontaneous activity (imp/s)	0.05 ± 0.024 (9/129)	0 ± 0 (0/27)	0.05 ± 0.03 (4/19)	0.05 ± 0.05 (1/11)	0.03 ± 0.02 (2/14)
Mechanical threshold (mN)	0.38 ± 0.03	0.31 ± 0.03	0.53 ± 0.14	0.26 ± 0.01	0.37 ± 0.08
n	146	27	19	11	14

Data are mean ± SEM; n = number of recorded fibers; number in brackets indicate the number of fibers with spontaneous activity/number of recorded fibers. No significant differences between groups were found.
