Motor Activity at PND 35 in MAO-inhibited and Control Mice.

Group	Locomotor Activity	Stereotypy Count	Margin Time	Center Time
A	1626 ± 135 cm	20.0 ± 2.1	157.3 ± 4.1 s	21.7 ± 4.1 s
B	1732 ± 173 cm	22.2 ± 2.4	150.2 ± 3.7 s	28.8 ± 3.7 s
AB	1571 ± 156 cm	18.3 ± 2.3	153.2 ± 4.1 s	25.8 ± 4.1 s
C	1970 ± 198 cm	15.5 ± 2.2	151.3 ± 3.2 s	27.7 ± 3.2 s

Behavioral measures (locomotor activity, incidence of stereotypies, performance in an open field test) were obtained as described in detail in Methods. Neither average locomotor activity (F_3,20 = 1.12, p = 0.37) nor number of stereotypies (F_3,20 = 1.55, p = 0.23) differed between experimental groups. Time spent along the sides (margin time; F_3,20 = 0.68, p = 0.57) or in the center of the open field also did not vary across groups (F_3,20 = 0.681, p = 0.57). Data are presented as mean ± standard error. A, monoamine oxidase (MAO) A enzyme-inhibited mice (n = 6); B, MAO-B enzyme-inhibited mice (n = 6); AB, MAO-A and MAO-B enzyme-inhibited mice (n = 6); C, control animals (n = 6).
