			With treatment groups combined, noradrenaline was increased (P = 0.0013) in males (1374.16 ± 208.04 pg/mL) as compared with females (2385.60 ± 208.04 pg/mL)
No. of jumps (per second)	1.08 x 10?19 ± 0.0004	0.0006 ± 0.0004	P = 0.3225
No. of rears (per second)	0.091 ± 0.007	0.038 ± 0.007	P < 0.0001
No. of digs (per second)	4.34 x 10?19 ± 0.0011	0.0035 ± 0.0011	P = 0.0262

All data are presented as mean ± SEM and are compared between the treatments of home cage and induction chamber. Any significant differences seen between sexes or order of treatment are presented in the Comments column.
