Tonic hindlimb extension in D2 and B6 mice^a treated with various doses of PTZ

Strain	Dose (mg/kg, s.c.)
	60	70	80	90
D2	0  ± 0 (7)	14  ± 7 (14)	90  ± 7 (20)	95  ± 5 (19)
B6	0  ± 0 (8)	0  ± 0 (10)	0  ± 0 (18)**	14  ± 13 (15)*
F1			80  ± 10 (15)
F2			65  ± 2 (511)

^F1-aValues represent the percentage (±SE) of animals exhibiting tonic hindlimb extension. The number in parentheses indicates the number of mice treated.

**p = 0.0014; *p = 0.0046 versus respective D2 value (Fisher’s Exact Test, two-tailed).
