Effects of acute treatment with BNN 27 on rats’ performance in the open field test

Treatment	Number of squares crossed	Number of rearings	Time spent in the central zone (s)	Grooming duration (s)
Vehicle	86.1 ± 3.3	32.3 ± 0.6	6.4 ± 2*	12.4 ± 2.7
BNN 27 (1 mg/kg)	98.4 ± 2.9	32.5 ± 0.7	9 ± 1.1	6.8 ± 2.3
BNN 27 (3 mg/kg)	94 ± 5.4	35.6 ± 1.1	14.5 ± 2.4	7.3 ± 1.3
BNN 27 (6 mg/kg)	99 ± 5.7	35.3 ± 1.7	14.3 ± 2.6	4.9 ± 1.1

Data are expressed as mean ± SEM. of eight rats per treatment group. Vehicle and BNN 27 were injected intraperitoneally 40 min before testing
