Percentage change in outward current in response to NA

Cell type	Control	Axotomy	Autotomy
Large	0	−24.5  ± 5.0%5-150	−31.4  ± 2.1%5-165
	(0/11)	(2/10)	(8/11)
Medium	0	−33.6  ± 2.6%5-160	−41.6  ± 3.5%5-165
	(0/13)	(8/10)	(10/11)
Small	0	−37.2  ± 3.1%5-165	−45.9  ± 2.6%5-165
	(0/14)	(11/14)	(12/12)

Negative changes indicate decreases in amplitude recorded at +70 mV from a holding potential of −90 mV. Numbers in parentheses indicate number of cells responding relative to number of cells tested. Percentage changes are calculated only from those cells that responded.

F5-150: p < 0.05;

F5-160: p < 0.005;

F5-165: p < 0.001. Comparisons of control currents with currents seen in the presence of NA (paired t test).
